Remarks

You can optimize table rendering performance by specifying the IHTMLCurrentStyle::tableLayout property. This property causes the table to be rendered one row at a time, providing users with information at a faster pace. The IHTMLCurrentStyle::tableLayout property determines column widths for a table in the following order:

By using information in the IHTMLImgElement::width property for the col or colGroup element.
By using information in the IHTMLImgElement::width property for the td elements in the first row.
By dividing the table columns equally, regardless of the size of the content.

If the content of a cell exceeds the fixed width of the column, the content is wrapped or, if wrapping is not possible, it is clipped. If the IHTMLCurrentStyle::tableLayout property is set to fixed, the IHTMLCurrentStyle::overflow property can be used to handle content that exceeds the width of a td element. If the row height is specified, wrapped text is clipped when it exceeds the set height.

Setting the property to fixed significantly improves table rendering speed, particularly for longer tables.

Setting row height further improves rendering speed, again enabling the parser to begin rendering the row without examining the content of each cell in the row to determine row height.

Examples

This example uses the CSS table-layout attribute to set the table layout to fixed.

<!DOCTYPE html>
<html>
<head>
  <title>table-layout</title>
</head>
<body>
  <table style="table-layout: fixed;">
    <tr>
      <td>&nbsp;</td>
      <td>&nbsp;</td>
    </tr>
    <tr>
      <td>&nbsp;</td>
      <td>&nbsp;</td>
    </tr>
  </table>
</body>
</html>
