Description

When the dataset contains 0 rows, an empty <tbody> is generated by DataTable. This is not valid XHTML strict.

According to XHTML 1.0 Strict:

• a <table> must at least contain one <tbody> or <tr>
• a <tbody> must contain at least one <tr>
• a <tr> must contain at least one <th> or <td>

I can only think of one possible solution and it's quite ugly: add an "invisible row" (either always, or only when there are 0 rows) just after the opening <tbody> tag in DataTable.html:
<tr style="display: none;"><td></td></tr>
