  }
  th, td {
    border: 1px solid #ddd;
    padding: 8px;
    text-align: left;
  }
  th {
    background-color: #0066cc;
    color: white;
  }
  tr:nth-child(even) {

Frequently asked questions

Key distinctions behind the tool.

Should every table have a header?

Prefer a header row for data tables so screen readers and humans can identify columns.

Can I style the table?

Yes—add CSS classes or inline styles after you paste the markup into your page.
