How to fix the height of rows in the table?

The height of rows ‘tr’ in a table can be fixed very easily. This can be done by adding the height attribute in the tr tag. If the height is not specified, the height of the row changes according to the content. The height can be specified either in pixels, or percentage.

Syntax:

<tr height="px | %">

Approach:

  • The height attribute is used to set the height of a row. It is added in the <tr> tag.
  • The height should be specified according to the content, either in pixels or percentage.
  • If the content in the row is large, it will overflow.

Example: In this example, the height of the first row has been fixed, but the height of the second row has not been. So, when we vary the size of the screen, the height of the first row remains the same, but the height of the second-row changes according to the content. However, if the specified height is not sufficiently large according to the content, this may not work, and the first row will overflow and behave similarly to the second row.

Run the following code and vary the screen-size to see the difference between both the rows:
