How to determine column width in word by openxml - openxml

I need create a word file and insert a grid in it by openxml.
So far, I know create grid like below will set the table width fit to window
TableProperties tblProps = new TableProperties();
tableWidth = new TableWidth() { Width = "5000", Type =TableWidthUnitValues.Pct };
TableStyle tableStyle = new TableStyle() { Val = "TableGrid" };
tblProps.Append(tableStyle, tableWidth);
table.Append(tblProps);
But how can I divide a row into some columns whose share same width. Because I don't know the width of the table, so I can't calculate the width of the columns.
And the column number in different row may be different.
Please help me, thanks

Google Visualization Table Column Width and Row Height

I have a panel on my site that has a Google Visualization Chart (Table) with controls and custom style. I have trouble with setting column width - somehow no solution works. Where is my mistake?
My two solutions:
a) like in row 57/58 in the code:
data.setProperty(0, 0, 'style', 'width:150px;');
b) like line 134-145 in the code:
google.visualization.events.addListener(table, 'ready', function() {
google.visualization.events.addListener(table.getChart(), 'sort', setWidth);
setWidth();
});
function setWidth() {
var title = 'Field4';
var width = '500px';
$('.google-visualization-table-th:contains(' + title + ')').css('width', width);
}
Also I didn't find any solution for limiting row height. If you select one row (eg. with Field4 filter) then this one row will fill all the space. Is there a way to limit row size to the content only?
This is my code: https://jsfiddle.net/my7p01e8/2/

Auto Size all columns to fit content

All my searches turned up for sizeColumnsToFit and autoSizeColumns which is not what I want.
My grids have many columns, so it scroll horizontal which is fine
But I cannot know in advance what would be the most space needed for the widest text in a column, so want the grid to auto size all columns to accommodate for whatever is the longest line of text in the cell.
Can one do that? (pretty much like have nowrap on a html table column, not that ag-grid wrap text, it just hide what is too long)
Grid Resizing:
https://www.ag-grid.com/javascript-grid-resizing/
sizeColumnsToFit - this tries to squeeze all the columns in the view - no horizontal scrolling
autoSizeAllColumns - this tries to size all columns to to fit the data - horizontal scrolling
// If you need to resize specific columns
var allColIds = params.columnApi.getAllColumns()
.map(column => column.colId);
params.columnApi.autoSizeColumns(allColIds);
// If you want to resize all columns
params.columnApi.autoSizeAllColumns();
I passed through this and it took me some time to make it work the way I wanted to, by that I mean :
Use all the available space
Make each column take the width required to display its content correctly
Solution :
Add the width parameter for each column (requires some manual tuning to set the right values)
Call gridApi.sizeColumnsToFit() in the onGridReady which will resize to take the available space while making sure that columns having bigger width will take more space
const gridOptions = {
...
columnDefs: [
{
...,
width: 100
},
{
...,
width: 50
},
...
],
...
onGridReady: (event) => event.api.sizeColumnsToFit();
};
Simply use flex instead of width in the column definitions. The grid will adjust automatically.
You can find a complete example for auto resizing all column.
column-sizing
Simply call autoSizeColumns() function, all columns will be resized according to content.
gridColumnApi.autoSizeColumns(allColumnIds, skipHeader);

iText -- How do I get the rendered dimensions of text?

I would like to find out information about the layout of text in a PdfPCell. I'm aware of BaseFont.getWidthPointKerned(), but I'm looking for more detailed information like:
How many lines would a string need if rendered in a cell of a given width (say, 30pt)? What would the height in points of the PdfPCell be?
Give me the prefix or suffix of a string that fits in a cell of a given width and height. That is, if I have to render the text "Today is a good day to die" in a specific font in a PdfPCell of width 12pt and height 20pt, what portion of the string would fit in the available space?
Where does iText break a given string when asked to render it in a cell of a given width?
This is with regard to iText 2.1.6. Thanks.
iText uses the ColumnText class to render content to a cell. This is explained in my book on page 98-99. This means that, just like with ColumnText, you need to make the distinction between text mode and composite mode.
In any case, ColumnText measures the width of the characters and tests if they fit the available width. If not, the text is split. You can change the split behavior in different ways: by introducing hyphenation or by defining a custom split character.
I've written a small proof of concept to show how you could implement custom "truncation" behavior. See the TruncateTextInCell example.
Instead of adding the content to the cell, I have an empty cell for which I define a cell event. I pass the long text "D2 is a cell with more content than we can fit into the cell." to this event.
In the event, I use a fancy algorithm: I want the text to be truncated in the middle and insert "..." at the place where I truncated the text.
BaseFont bf = BaseFont.createFont();
Font font = new Font(bf, 12);
float availableWidth = position.getWidth();
int contentLength = content.length();
int leftChar = 0;
int rightChar = contentLength - 1;
availableWidth -= bf.getWidthPoint("...", 12);
while (leftChar < contentLength && rightChar != leftChar) {
availableWidth -= bf.getWidthPoint(content.charAt(leftChar), 12);
if (availableWidth > 0)
leftChar++;
else
break;
availableWidth -= bf.getWidthPoint(content.charAt(rightChar), 12);
if (availableWidth > 0)
rightChar--;
else
break;
}
String newContent = content.substring(0, leftChar) + "..." + content.substring(rightChar);
PdfContentByte canvas = canvases[PdfPTable.TEXTCANVAS];
ColumnText ct = new ColumnText(canvas);
ct.setSimpleColumn(position);
ct.addElement(new Paragraph(newContent, font));
ct.go();
As you can see, we get the available width from the position parameter and we check how many characters match, alternating between a character at the start and a character at the end of the content.
The result is shown in the resulting PDF: the content is truncated like this: "D2 is a c... the cell."
Your question about "how many lines" can be solved in a similar way. The ColumnText class has a getLinesWritten() method that gives you that information. You can find more info about positioning a ColumnText object in my answer to your other question: Can I tell iText how to clip text to fit in a cell

How to change cell color in a listgrid

I want to change font and color of a specific cell in a ListGrid.
I succeeded to change the color of the entire row with the following lines, but not of a single row:
for (ListGrid table : tables)
{
ListGridField[] columns = table.getFields();
for (Record record : table.getRecords())
{
....
record.setAttribute("cssText",
"font-weight:bold; font-size:80%; color:#FF3300;");
I don't want to use getCellCSSText function, i tried the following but it didn't work:
ListGridField gridfield = table.getField(columns[1].getName());
gridfield.setAttribute("cssText",
"font-weight:bold; font-size:80%; color:#FF3300;");
table.refreshFields();
I'm sure there is a better way to do it. But this is how i did it:
I added a hidden column to the table, that contain the color.
In getCellCSSText i read the color and the column name and set the color.
Is there a way to add an invisible parameter to a ListGridRecord? So that i won't add an entire column.

Setting Alignment for each Element when more than one Element added to a PDFPcell

In a table, I have a few cells that contain multiple elements. For Example, to indicate address , the cell may contain a phrase containing an "ADDRESS:" header Chunk followed by another chunk containing the actual address:
FROM: -- Chunk 1 in Phrase
123 Main St, Some City, ST -- Chunk 2 in Phrase
As of now, to align the cell contents, I am using the following code in the PDFPcell:
cell.VerticalAlignment = Element.ALIGN_MIDDLE;
However, this aligns all of the cell contents to the middle of the cell. If I want to put Chunk 1 at TOP_LEFT and Chunk 2 at BOTTOM_LEFT, is it possible to achieve it with iTextSharp? Essentially, I am looking for a way to align various elements within a cell at different locations.
Unfortunately the only way to do what you want is to add a sub-table in place of your multiple chunks.
t.AddCell("Row 1");
PdfPTable subTable = new PdfPTable(1);
subTable.DefaultCell.VerticalAlignment = Element.ALIGN_TOP;
subTable.DefaultCell.HorizontalAlignment = Element.ALIGN_LEFT;
subTable.AddCell("Top Align");
subTable.DefaultCell.VerticalAlignment = Element.ALIGN_BOTTOM;
subTable.DefaultCell.HorizontalAlignment = Element.ALIGN_RIGHT;
subTable.AddCell("Bottom Align");
t.AddCell(subTable);
doc.Add(t);
