Syntax

width=" { number | percentage } "

Description

Unless a width is set, a td (and the th) will take up only the width it requires (obviously this will depend on the amount of content in each table cell). You can use the width attribute in the context of the col element to fix the column’s width to a value of your choosing, regardless of the content of the table cell.

Example

The width attribute for each column is set to a larger value than that of the column to its left:

<table border="1" cellpadding="5">
  <col width="100"/>
  <col width="150"/>
  <col width="200"/>
  <col width="250"/>
  <tr>
    <th colspan="4" scope="col">Work Contact Points</th>
  </tr>
  <tr>
    <th>Name</th>
    <th>Email</th>
    <th>Phone</th>
    <th>Floor/Block</th>
  </tr>
  ⋮
</table>

Value

This attribute takes as its value a number representing the width of the column element in pixels, or a percentage.
