How Can I Make Empty Table Cell Borders Visible in Internet Explorer 7?

CSS for Empty Cell Border Display

Question:

How can I use CSS to ensure that a table cell's border remains visible, even when the cell is empty?

Specific Context:

The requirement applies specifically to Internet Explorer 7.

Answer:

In some versions of Internet Explorer, empty cells may not appear unless they contain content. To address this issue:

• Non-breaking Space: Insert an HTML non-breaking space character ( ) into the empty cell. This will typically fill the void and display the border.
• Pure CSS Solution: In Internet Explorer 8 and later, the empty-cells property controls cell visibility. Set it to show to display empty cells. However, this property is not supported in IE7, so an alternative approach is required.

For IE7, there is no built-in CSS solution to display empty cell borders. As a workaround:

• Add Content: Consider adding minimal content, such as a small dot (.) or a single character, to the empty cell.
• Create a Pseudo-Element: Use the ::before or ::after pseudo-elements to create an invisible element that occupies the empty space and displays the desired border.
