How to Make Table Cell Links Span the Entire Row Height?

Expanding Table Cell Links to Fill Row Height

When creating tables with cells that contain links, it's desirable to enable the user to click anywhere within a cell and trigger the link's action. However, when cells span multiple lines while others in the same row have fewer lines, the shorter cells may not fill the entire vertical space of the row.

To address this issue, a common approach is to set the linked elements within the cells to behave as block elements using the display: block property. This allows the links to expand to the full width and height of the cell. However, in cases where some cells have multiple lines, the one-line cells can still appear visually shorter.

A solution to this problem is to apply a negative margin and equal padding to the block element. The negative margin ensures that the block element expands beyond the boundaries of the cell, while the padding prevents the text from overlapping the cell's content. Additionally, setting the overflow property of the parent table cell to hidden prevents the overflow of content outside the cell's boundaries.

Consider the following updated CSS code:

td {
    overflow: hidden;
}
td a {
    display: block;
    margin: -10em;
    padding: 10em;
}

With these adjustments, the links within table cells will stretch to fill the entire row height, ensuring a consistent appearance for all cells, regardless of their content length.
