Exec insertOrderedList twice in all the cells of a table row removes the previously inserted list items:

Before:
| <table>
|   border="1"
|   <tbody>
|     <tr>
|       id="element"
|       <td>
|         "<#selection-anchor>fsdf"
|       <td>
|         "fsdf"
|     <tr>
|       <td>
|         <#selection-focus>
|         "gghfg"
|       <td>
|         "fsfg"

After:
| <table>
|   border="1"
|   <tbody>
|     <tr>
|       id="element"
|       <td>
|         "<#selection-anchor>fsdf"
|         <br>
|       <td>
|         "fsdf<#selection-focus>"
|         <br>
|     <tr>
|       <td>
|         "gghfg"
|       <td>
|         "fsfg"
