Question

I have a HTML table as shown in http://jsfiddle.net/Lijo/JN8Pm/1/ . This table is generated by gridview in asp.net. Hence I cannot add a class to “td” inside “tr”. [This is the suggestion in many forums; but that won’t work for me due to gridview]

How can I

1. set the background color of Emp ID column as Red?
2. set the width of Emp ID column as 300px?

Reference:

Refer the following two for table styling

1. table-layout:fixed;
2. word-wrap:break-word;

1. Using "word-wrap: break-word" within a table
2. Word-wrap in an HTML table
3. Adjusting HTML Table Cell Width using jQuery
4. Table cells get hidden when total width is more than 100%

Answer 1

You can see live example here: http://jsfiddle.net/JN8Pm/8/

var table = $('#detailContentPlaceholder_grdTransactions'),
    trs = table.find('tr'),
    headTr = table.find('.second'),
    empHeader = $($(headTr).children('th')[1]);

table.width(table.width() + 300);

empHeader.css('background-color', 'red');
empHeader.width(300);

for (var i = 2; i < trs.length; i += 1) {    
    var td = $($(trs[i]).children('td')[1]);
    td.css('background-color', 'red');
    td.width(10);
}​

It’s changing the color and the size of the EmplID column.
I hope that this is solving your problem.
