<tbody>
The block of rows holding the table's data.

When to use it
Explicitly wrap data rows; multiple tbody elements can group related row batches.
When not to
Browsers insert one implicitly, but writing it keeps the structure honest and styleable.
Example
<tbody>
<tr><th scope='row'>Monday</th><td>18</td></tr>
<tr><th scope='row'>Tuesday</th><td>25</td></tr>
