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
Images for all three versions above:
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>
<td align="center">Key Features<br>

As part of a test scrip I have to redirect to a 3rd party hosted payment page. However, when I try and find the input box elements it errors slightly differently depending on which call I try:
$driver->find_element_by_id("card.billingAddress.houseNumberOrName")->clear
returns "Element is not currently visible and so may not be interacted with"
$driver->find_element_by_xpath('//input[#id="card.billingAddress.houseNumberOrName"')->clear
returns "SyntaxError: The expression is not a legal expression."
The source of the section I am searching is:
<tr>
<td colspan="2"><div class="fieldSubHeader">Billing Address</div>
</td>
</tr>
<tr>
<td><div id="idAddress1_card" style="display:inline">Address 1</div>
<div id="idHouseNumberOrName_card" style="display:none">House Number/Name
</div</td>
<td><div class="fieldDiv" id="idDivAddress1_card">
<input type="text" class="inputField" id="card.billingAddress.houseNumberOrName" name="card.billingAddress.houseNumberOrName" value="" size="15" maxlength="40" />
</div></td>
</tr>
Is it the . in the ID that is causing the issue?
(I have checked the computed CSS and it is not hidden!)
Many thanks
You are missing the closing ]. Replace:
'//input[#id="card.billingAddress.houseNumberOrName"'
with:
'//input[#id="card.billingAddress.houseNumberOrName"]'
HERE ^
Note that you might simplify it by switching directly to the find_element_by_id() method.
Basically, in English I want to tell Selenium "look for the content ttc202 in column one, of a multi-row, multicolumn table, then mouseOver on the Edit link"
HTML is as follows:
<tr id="86" class="ui-widget-content jqgrow ui-row-ltr ui-state-highlight" tabindex="0" role="row" aria-selected="true">
<td aria-describedby="jqLst_Short Name" style="text-align:left;" role="gridcell">
ttc202
</td>
<td aria-describedby="jqLst_Long Name" style="text-align:left;" role="gridcell">
Testing Training Company 202
</td>
<td aria-describedby="jqLst_Actions" title="" style="text-align:center;" role="gridcell">
<a class="act avw" title="View this Organisation" href="company/view?lcId=86"></a>
<a class="act aed" title="Edit this Organisation" href="company/edit?lcId=86"></a>
</td>
</tr>
I have tried this:
//td[contains(text(),'ttc202')]/following-sibling::td[contains(a/title(),'Edit this Organisation')]/a
All help appreciated. I assume I am missing something to skip over the first column, but can't imagine what will enable me to do that...
Progress:
I have found the following as an alternative which should get to the correct cell, but I am not able to workout how to target the title in the link code:
//td[normalize-space() ="ttc202"])[1]/following-sibling::td[2]/a[. = 'Edit']
I think this is progress just not sufficient to get me to the finish line!
After much investigation I found the following answer, perhaps this might help others who come across this question:
//tr[contains(td[1], "ttc202")]/td[3]/a[#title='Edit this Organisation']
The trick was realising which cell the information was in (represented by the square brackets).
I'm building a MailChimp template and would like to have nested repeatable variants. Something like this
-- Variant 1A
-- Variant 2A
-- Variant 2B
-- Variant 1B
-- Variant 3A
-- Variant 3B
-- Variant 1C
-- Variant 4A
-- Variant 4B
When I nest mc:repeatable="" and mc:variant="" elements inside another repeatable/variant tag it doesn't work. The inner repeatables don't appear in the editor. Removing the inner repeatable/variant tags makes the content appear again, but the ability to repeat the content blocks is lost obviously.
Here's a full example of the code:
<tr mc:repeatable>
<td>
<table>
<tr mc:repeatable="rating" mc:variant="variant1">
<td>
<div mc:edit="text">
</div>
</td>
</tr>
<tr mc:repeatable="rating" mc:variant="variant2">
<td>
<div mc:edit="text">
</div>
</td>
</tr>
</table>
</td>
</tr>
Has anyone been able to nest repeatable/variant blocks in a MailChimp template?
Looking at mc:repeatable in MailChimp's Reference apparently it is possible to nest repeatable elements within repeatable elements, though it's "not encouraged"
http://templates.mailchimp.com/getting-started/template-language/
I'm also trying to do something similar, from what I can tell, it doesn't seem possible to use a mc:variant inside a mc:repeatable and have it work the way we want.
Using the following:
<div mc:repeatable="repeat-wrapper">
<h1>Repeat wrapper</h1>
<tr>
<td>
<div mc:repeatable="catsdogsbirdsfish"
mc:variant="meow meow meow!">
<h1>Meow!</h1>
Cats are the best!
</div>
<div mc:repeatable="catsdogsbirdsfish"
mc:variant="woof woof woof!">
<h1>Woof!</h1>
Dogs are the best!
</div>
<div mc:repeatable="catsdogsbirdsfish"
mc:variant="tweet tweet tweet!">
<h1>Tweet!</h1>
Birds are the best!
</div>
<div mc:repeatable="catsdogsbirdsfish"
mc:variant="glub glub glub!">
<h1>Glub?</h1>
I don't know what sounds fish make,
but they are the best!
</div>
</td>
<td><p>End of the repeating element</p></td>
</tr>
</div>
I could create and repeat any number of Cats, Dogs, Birds or Fish. The repeating UI appeared along with the variant dropdown selector. I could also create a new Repeat Wrapper but I could not insert any Cats, Dogs or Birds inside the newly repeated container :/
You can't nest repeatable within repeatable
From MailChimp:
The mc:repeatable attribute defines a content block that can be
repeatedly added to the template. When using mc:repeatable, make sure
to use proper nesting of items. An mc:repeatable section should never
be contained within an mc:edit section. Instead, nest your mc:edit
sections within your mc:repeatable blocks. Never nest mc:repeatable
blocks within other mc:repeatable blocks, mc:edit areas within other
mc:edit areas, or mc:edit images within mc:edit areas.
I'm working on a small problem where I'm trying to show/hide a panel based on two criteria
A specific data field must not be blank
The specific data filed must also not equal "Not Relocatable"
Unfortunately this doesn't seem to be working for me (note that setting either one or the other criteria works just fine.)
<asp:Panel runat="server" Visible='<%#If(Not String.IsNullOrEmpty(DataBinder.Eval(Container.DataItem, "_236")) Or Not DataBinder.Eval(Container.DataItem, "_236") = "Not Relocatable", True, False)%>'>
<tr>
<td>
</td>
<td class="align-right lightgreen">
Buyer would consider relocating a business, if it is:
</td>
<td>
</td>
<td colspan="3">
<%#DataBinder.Eval(Container.DataItem, "_236")%>
</td>
<td>
</td>
</tr>
</asp:Panel>
Can anyone lend a hand to rectify this problem for me?
The syntax <%# %> is a data binding syntax, not an inline expression syntax. You cannot use procedural code inside of it like you can in the inline code <% %> tags.
Data binding tags must contain a single Eval or Bind function. If you need to do conditional branching based on those functions, you will need to do it using inline code around the binding tags.
