Unwanted HTML gap/space
Using Jamroom
Looking closer at this, these breaks must be part of the "pasting" process - JR is not adding them in. I just pasted this table:
<table> <tr> <td>One</td> <td>Tow</td> </tr> <tr> <td>Three</td> <td>Four</td> </tr> </table>
And here's the output it produced:
<div id="widget_id-189" data-id="189" class="sb-widget-content">
<div class="widget-item widget-item-widget_html">
<div class="item">
<table><tbody>
<tr>
<td>One</td>
<td>Tow</td>
</tr>
<tr>
<td>Three</td>
<td>Four</td>
</tr>
</tbody></table>
</div>
</div>
</div>So the extra line breaks are part of what you are pasting in. I assume you are clicking on the "code" button in the editor and pasting in your HTML? If you are trying to paste HTML directly into the editor (not using the code button) then it's not going to work correctly.
Let me know if that helps.
