Why Does IE Ignore Height for Table Cells When Using Display: Table?

IE Disregards Height for Table Cells

When employing display: table, display: table-row, and display: table-cell properties to construct a table, an unexpected issue arises in Internet Explorer (IE8 and potentially later versions). The height: 100% specified for the div containing the content is ignored.

Undefined Specification

This behavior stems from an ambiguity in the CSS specification. According to CanIUse, IE should provide full support for these layout properties. However, CSS 2.1 remains unclear on how height should be determined for display: table-row and display: table-cell elements using percentage values.

Cross-Browser Support Challenges

This undefined specification has led to inconsistent implementation across browsers. While a browser may claim full support, the precise behavior for height calculations may vary. This inconsistency renders cross-browser compatibility challenging.

Alternative Solution

Since a pure CSS workaround is not viable due to the undefined specification and IE's unique interpretation, alternative solutions must be explored. JavaScript-based approaches or fixed heights are potential options, but they may not be ideal for all scenarios.

Deprecation Awareness

It's crucial to note that display: table-cell and the associated properties are considered deprecated in the latest CSS specifications, replaced by the more versatile flexbox and CSS Grid layouts. While these alternative layouts offer similar functionality, they address the limitations of table layouts and provide greater control over height and sizing.
