Some table cells may not be displayed in Internet Explorer 8 and in Internet Explorer 9 when the table contains several columns that contain different colspan attributes

Consider the following scenario:

• You have a webpage that contains a table.
• The table has several columns, and the columns contain different colspan attributes.
• The colspan attributes contain tables that have the "table-layout: fixed" style attribute.�
• You use Windows Internet Explorer 8 or Windows Internet Explorer 9 to open the webpage.

In this scenario, the width of the columns is calculated incorrectly. Therefore, some cells are moved out of the visible area and cannot not be displayed.

Notes

• This issue occurs when you use Internet Explorer 8 Quirks mode and Internet Explorer 9 Standards mode.
• The issue does not occur when you use Internet Explorer 8 Standards mode.
