Table row styling with CSS Grid

Recently I ran into styling issues with a table layout where a lot of columns had to take the minimum amount of space, so certain other columns could take all the room available. The default table styling in CSS is not very flexible, so it would be great to use CSS Grid row such a layout. But with a normal CSS Grid layout you will not have the option to easily style even / odd row backgrounds. When searching how to style even / odd row backgrounds, the suggestions online were pretty outdated. Since subgrid support has become widely available, I think there are better solutions.

An example table

Programming Language Creator First Release
C Dennis Ritchie 1972
Python Guido van Rossum 1991
JavaScript Brendan Eich 1995

The code

To create the table above, we can use the HTML:

      <th>Programming Language</th>
      <th>First Release</th>
      <td>Dennis Ritchie</td>
    <!-- [...additional rows] -->

And the styling to make it into a CSS Grid based table:

table {
  display: grid; 
  grid-template-columns: repeat(3, 1fr); /* 3 columns of even width */
thead, tbody, tr {
  display: grid; 
  grid-template-columns: subgrid; /* thead, tbody and tr are subgrid */
  grid-column: 1 / -1; /* from the first to the last column */
thead tr, tbody tr:nth-of-type(even) {
  background-color: white; /* the header and even rows get alternative background-color */
th {
  font-weight: bold;

The code above is a very simplified example, but with CSS Grid and subgrid the options for creating advanced table layouts are almost limitless.
