Table cells may be displayed in the wrong location when opening large HTML files in Excel 2003, Excel 2007, Excel 2010 or Excel 2013.
This can occur if there is a <td> tag that contains a <br> with a large number of rows or cells spanning multiple rows and columns.
For example: <td >Test Text<br>Test Text</td>
Workaround:
Edit the HTML and remove the <br> tags from the table using a tool such as Notepad++.
