+Table headers are actually. But come on, you want them, don’t you? If you don’t want them, update the `content` attribute of the [`TableRow`](/api/nodes/table-row) extension, like this:
+
+```js
+// Table rows without table headers
+TableRow.extend({
+  content: 'tableCell*',
+})
+```
+
+This is the default, which allows table headers:
+
+```js
+// Table rows with table headers (default)
+TableRow.extend({
+  content: '(tableCell | tableHeader)*',
+})
+```

+Nothing is as much fun as a good old HTML table. The `Table` extension enables you to add this holy grail of WYSIWYG editing to your editor.

+Don’t forget to add a `spacer.gif`. (Just joking. If you don’t know what that is, don’t listen.)
