Element 'th' cannot be nested in element 'table'

html, html-table, w3c-validation

Solution

You cannot have the `<th>` element outside of a `<tr>`, the following snippet is valid

<table>
    <thead>
        <tr>
            <th>ID</th>
            <th>text header</th>
        </tr>
    </thead>
    <tbody>
    <tr>
        <td>7</td>
        <td>text</td>
    </tr>
    <tbody>
</table>

Permitted parent elements

A `<tr>` element.

Problem

Given the following HTML, why do you get the error: Validation (HTML5): Element 'th' cannot be nested in element 'table' ``` <table> <th>ID</th> <th>text header</th> <tr> <td>7</td> <td>text</td> </tr> </table> ```
