The following will throw error (no <thead> and <tbody> tags)

<table id="sample-table">
    <tr>
        <th>title-1</th>
        <th>title-2</th>
    </tr>
    <tr>
        <td>data-1</td>
        <td>data-2</td>
    </tr>
</table>
  
The following will also throw an error (unequal number of columns)

<table id="sample-table">
    <thead>
        <tr>
            <th>title-1</th>
            <th>title-2</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>data-1</td>
            <td>data-2</td>
            <td>data-3</td>
        </tr>
    </tbody>
</table>
