Dreamweaver Lock table
This is a better question for Stack Overflow, but this should probably be done with CSS. For this simple example, I specified the width in pixels instead of a percentage. If you must override widths and have particular columns be different widths, then you should could do inline style for the table cells, or put &lt;column /&gt; tags at the top of the table, and specify the width with those (that part wasn't in the JSFiddle). Note that you may need to use CSS to help with line breaks as well if you don't have any spaces in your text.
