Is it possible to have a table in the center in a GitHub gist Markdown? If so, how?
I've used the following syntax to create a table on a Markdown file:
Somehow the table is always flushed to the left!!!
|Column1|Column1|Column1|
|:----|:----:|----:|
|Column1|Column1|Column1|
But the table is flushed left, see https://gist.github.com/alvations/5095d3bcc0eec357c78f1c21a49e334f
Is it possible to have the table at the center of the page when viewing?
I've tried the suggestion from Is it possible to center tables in a markdown file? to use:
Somehow the table is always flushed to the left!!!
<center>
|Column1|Column1|Column1|
|:----|:----:|----:|
|Column1|Column1|Column1|
</center>
And the table disappears when viewing, see https://gist.github.com/alvations/cd3495e7107b7701cf1cf1da2a839534
I've also tried How do I center an image in the README.md on GitHub?:
Still on the left!!!
<p align="center">
|Column1|Column1|Column1|
|:----|:----:|----:|
|Column1|Column1|Column1|
</p>
But it's still on the left, see https://gist.github.com/alvations/23c18681df7a6bbf175d0e8c2cfccba3

In short, it's not possible. GitHub does not allow you to define your own styling.
First, note that there is no mention of the ability to apply any styling to any block level types in the GitHub Flavored Markdown spec (see the tables section). As your examples show, you are aware that you can center text within table cells, but that only applies to the cells and has no effect on the parent table (which is how HTML and CSS work and is not specific to Markdown or GitHub).
There are a few ways to define custom styles for HTML (which Markdown generates), but GitHub does not permit them.
One such way is to define CSS rules. However, right in the spec, GitHub explicitly states that they do not allow <style> tags.
Another way is to include raw HTML right in the Markdown document (with inline styles). However, for security reasons, GitHub is very selective about what they allow. In the Markup project they define the filters they apply to all markup languages they support (including, but not limited to Markdown). In pertinent part, the docs explain (emphasis added):
The HTML is sanitized, aggressively removing things that could harm you and your kin—such as script tags, inline-styles, and class or id attributes. See the sanitization filter for the full whitelist.
Given the above, it is simply not possible to define your own styling for documents hosted on GitHub. That said, some expect to be able to define styling within the Markdown syntax itself. However, the original Markdown rules explain (emphasis added):
Markdown’s syntax is intended for one purpose: to be used as a format for writing for the web.
Markdown is not a replacement for HTML, or even close to it. Its syntax is very small, corresponding only to a very small subset of HTML tags. The idea is not to create a syntax that makes it easier to insert HTML tags. In my opinion, HTML tags are already easy to insert. The idea for Markdown is to make it easy to read, write, and edit prose. HTML is a publishing format; Markdown is a writing format. Thus, Markdown’s formatting syntax only addresses issues that can be conveyed in plain text.
For any markup that is not covered by Markdown’s syntax, you simply use HTML itself.
As it is not a "publishing format," providing a way to style your document is out-of-scope for Markdown. Which leaves us with the ways which GitHub explicitly disallows. Therefore it is not possible to center a table (or apply any other custom styling) on GitHub.
As an aside, while GitHub uses the CommonMark spec (with extensions) rather than the original Markdown Rules, I make reference to the original rules as the section I quote from discusses the philosophy behind various design decisions made when creating Markdown. Markdown's (and CommonMark's) behaviors are directly related to that philosophy. While the CommonMark spec does not get into the design decisions (expect when it differs from Markdown), it does make reference to some of the points discussed in the very paragraph I quoted above. And nowhere does it contradict that philosophy. Therefore, I consider it relevant to the expectations we should have about what is and what is not part of CommonMark, and by extension, GitHub Flavored Markdown.
For completness, let's examine each of the examples provided by the OP.
The first example is simply a table with the middle column aligned "center". If we "view source" (or use the browser's "inspect" tool), we see the following HTML was generated:
<table>
<thead>
<tr>
<th align="left">Column1</th>
<th align="center">Column1</th>
<th align="right">Column1</th>
</tr>
</thead>
<tbody>
<tr>
<td align="left">Column1</td>
<td align="center">Column1</td>
<td align="right">Column1</td>
</tr>
</tbody>
</table>
Note that align="center" is only defined on the middle cell of each row. As such styling is only inherited by children elements, not parent elements, this does not get applied to the the table as a whole.
As an aside, the align attribute is not even mentioned in the HTML5 spec (that I could find); however, in the HTML 4.01 spec, you can define an align attribute on a table element or any of its children which is then inherited by the children of that element only.
Of course as established above, Markdown does not provide a mechanism to define alignment on anything except the cells. But even if you could define align on the table element, the spec explains that "[t]his attribute specifies the alignment of data and the justification of text in a cell."
Therefore, if would still have no effect on how the table is positioned in its parent element.
The second example is a table wrapped in a <center> element. A look at the source HTML reveals that the <center> tag was stripped out.
In fact, a look at GitHub's whitelisted elements reveals that center elements are not allowed and stripped out.
The third example attempts to wrap the table in a paragraph with align="center" defined on the paragraph. However, note the (interpreted) HTML:
<p align="center"></p>
<table>
<thead>
<tr>
<th align="left">Column1</th>
<th align="center">Column1</th>
<th align="right">Column1</th>
</tr>
</thead>
<tbody>
<tr>
<td align="left">Column1</td>
<td align="center">Column1</td>
<td align="right">Column1</td>
</tr>
</tbody>
</table>
<p></p>
According to the HTML5 spec:
A p element's end tag may be omitted if the p element is immediately followed by an... table... element.
Therefore, the paragraph does not actually wrap the table, but is implicitly closed by the table's opening tag.
But that got me curious. What if you used a div instead of a paragraph. But that makes no difference. As we've established earlier, the align attribute only effects cell text. You need to assign a style to change the position of a table on the page and Github explicitly disallows defining your own styles.
As you can see in the following image, GitHub automatically renders tables so that they're already taking up the full width. Because of this, you cannot center the text that GitHub's Markdown renderer generates (aka the table is really, really fat and technically already centered).
So totally possible !
<div align="center">
COLUMN 1 | </br>COLUMN 2 | </br></br>COLUMN 3
:--- | :---: | ---:
</br></br>left | center | </br></br>right
</div>
: Spacer
</br> : Skip line
:--- : Left
:---: : Center
---: : Right
It is possible to center a table. Essentially, on GitHub the table is already width 100%. You just need to give the tbody enough content for it take up 100% width too.
The trick: fill it with spaces.
<table>

<tr>

I have a form that is using the calendar/date selection tool within Ektron, but when users select the current date (or any date, for that matter), it gives an error saying that you need to select a date in the past.
We haven't tooled around in the code for this form, but it almost sounds like a validation issue.
Here's the code, as is, from Ektron.
<p align="center" style="text-align: left;">Date program was presented:
<ektdesignns_calendar title="Date presented" id="Date_presented" onblur="design_validate_xpath('number(translate(.,\'-\',\'\')) <= number(translate($currentDate,\'-\',\'\'))',this,'Date in the past (required)');" ektdesignns_name="Date_presented" ektdesignns_caption="Date presented" ektdesignns_invalidmsg="Date in the past (required)" ektdesignns_validate="xpath:number(translate(.,'-','')) <= number(translate($currentDate,'-',''))" ektdesignns_basetype="calendar" ektdesignns_datatype="date" ektdesignns_validation="datePast-req" name="Date_presented">
<input type="text" size="30" readonly="readonly" unselectable="on" />
<img width="16" height="16" class="design_fieldbutton" alt="Select date" src="[skinpath]btncalendar.gif" unselectable="on" /></ektdesignns_calendar></p>
My knowledge on validation is limited, but it looks like it's parsing the date as an integer. Is it possible to add a day (+1) to the current date so that it interprets any day as valid as long as it's not in the future?
I guess this is a HTML form as opposed to a Smart form?
If so, have you checked the validation settings on the calendar field? If you edit the form, right-click on the field and choose Field Properties you will get the properties window. Go to the Validation tab and check the setting in the Validation drop down.
There are options for ensuring the date is in the past or the future. Perhaps one of these options has been set?
I have a problem with pagination.
In my website , I have a function productList which generates a paginated list of products.
The code for the paginate function is shown below:
$this->paginate = array('conditions'=>array($otherconditions,$statuscondition,$active_condition,$catcondition),'order' => $order, 'limit' => 10);
In the view file,
the paginator helper is used as follows:
<div class="paginator">
<span class="info">
<?php echo $this->Paginator->counter(array('format' => __('Page <strong>{:page}</strong> of <strong>{:pages}</strong>')), array('escape'=>false));
?>
</span>
<ul>
<?php echo $this->Paginator->numbers(array('separator' => '', 'tag'=>'li'));?>
</ul>
</div>
Suppose, there are 150 products, so with a limit of 10, there will be 15 pages.
The problem is that the page numbers are not displayed in the end pages like page 15 i.e when I click on the page number 15, the products are displayed but the paginator counter and paginator number links are not displayed.
I have looked all over the net for a solution but could not find one. Please guide me.
PS: the paginate variable depends on my parameters like the category selected , and other conditions.
I dont think its a problem with the paginate syntax because the pagination works for small number of pages like 2 or 3.
The problem is with paginator helper I think.
Thanks in advance.
I have found the following line when I inspected the HTML. the page number and counter where commented automatically inside the following comments.
<!--[if gte mso 9]><xml>
<w:WordDocument>
<w:View>Normal</w:View>
<w:Zoom>0</w:Zoom>
<w:TrackMoves/>
<w:TrackFormatting/>
<w:PunctuationKerning/>
<w:ValidateAgainstSchemas/>
<w:SaveIfXMLInvalid>false</w:SaveIfXMLInvalid>
<w:IgnoreMixedContent>false</w:IgnoreMixedContent>
<w:AlwaysShowPlaceholderText>false</w:AlwaysShowPlaceholderText>
<w:DoNotPromoteQF/>
<w:LidThemeOther>EN-US</w:LidThemeOther>
<w:LidThemeAsian>X-NONE</w:LidThemeAsian>
<w:LidThemeComplexScript>X-NONE</w:LidThemeComplexScript>
<w:Compatibility>
<w:BreakWrappedTables/>
<w:SnapToGridInCell/>
<w:WrapTextWithPunct/>
< ...</p></div>
then after this I have the html for the page counter , page number links and also the script files. what is happening. I looked for its meaning and I found that mso 9 is microsoft office 9 or something. Which is not very reasonable. please guid me.
I solved this by putting a comment before the closing p tag and div tag.
So the comment tag <!--[if gte mso 9] > closes before </p></div>.
I also used the php function strip_tags to strip the body of text of all tags.
This is a duct tape method. But the problem I found lies in the mce editor.When a user copy pastes a paragraph from a word document to a mce editor thats running in firefox browser, the above mentioned conditional comment is added to the text. So, when displaying the user text, the conditional comment comments out rest of the html after the text.
IT is better to work with the mce editor callback to remove the conditional comment which i will be working on now.
Hope this helps someone...
I have an html email .oft (Outlook File Template) created in Outlook 2010 with a table layout width set to 600px. This ecard template is distributed to others at the company who might want to add a few lines of texts and signature to the bottom after the table.
However all the added text appears on the top right next to the table. How can I either block any content on the right of the table or set the width of the email to be only 600px so any new additions will appear correctly at the bottom after the table? I know that floats and clear css don't work reliably across in html emails.
Thanks, Attila
Your best bet would be to create a table at 100% width. Inside that table, make two cells, one with a width of 600, and another with a width of 'auto'. THis will then span the full remaining width of the email window.
This is not an ideal situation, but as you have mentioned, there are very tight limitations on what is achievable in MS Outlook 2010, let alone 2007.
Something like this:
<table><tr>
<td width="600">Enter details here</td>
<td> (space character so no client disregards this cell) </td>
</tr></table>
You may need to experiment with the width of that last cell, you could try and make it 100% or something to force the take up of all extra space on the right, but it will come down to your code, and your email, and what works best for that organization.
If that doesn't work, consider a nested table inside the first table to be extra sure...
<table width="100"><tr>
<td width="100%">
<table width="600"><tr>
<td width="600">Enter details here</td>
</tr></table>
</td>
<td> (space character so no client disregards this cell) </td>
</tr></table>
As a guide - I use the Campaign Monitor reference for compatibilities:
http://www.campaignmonitor.com/css/ - download the XLS file on that page.
Good luck.
I am checking on HTML content on my page, and I've got the split down to have the variable left with this content:
">
<td>Oklahoma City</td>
<td>Oklahoma</td>
<td>OK</td>
<td>405</td>
<td>CST</td>
</tr>
</table>
<div id="
Those are dynamic pages I'm checking, so the data will always be different, but the layout the same...
How can I get the value out of the second <td> if that html is in 1 variable(string)?
It was a full page, I've used explode twice to remove everything above a div field and everything below the last dive field id... so it has some open html tags left because I did not know how to get rid of that along the way to be left with just this:
<td>Oklahoma City</td>
<td>Oklahoma</td>
<td>OK</td>
<td>405</td>
<td>CST</td>
</tr>
</table>
Can you tell me how to get that out? I just need the second one because it is the county and that is what I'm checking on...
