Styling HTML Tables with CSS

Tables in the past were greatly overused in CSS, as they were one of the only ways we could create a fancy page layout.

Today with Grid and Flexbox we can move tables back to the job they were intended to do: styling tables.

Let’s start from the HTML. This is a basic table:

<table>
  <thead>
    <tr>
      <th scope="col">Name</th>
      <th scope="col">Age</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th scope="row">Flavio</th>
      <td>36</td>
    </tr>
    <tr>
      <th scope="row">Roger</th>
      <td>7</td>
    </tr>
  </tbody>
</table>

We can apply it on the table element, and on the inner elements too, like th and td:

table, th, td {
  border: 1px solid #333;
}

tbody tr:nth-child(odd) {
  background-color: #af47ff;
}

This gives us:

If you add border-collapse: collapse; to the table element, all borders are collapsed into one:
