You've completed your table columns and suddenly decide you need column heads? Don't panic it's quite simple. Copy and paste the code below:

<tr>
<td style="border: 1px solid #000000; width: 140px; text-align: center; line-height: 0pt;"></td>
<td style="border: 1px solid #000000; width: 140px; text-align: center; line-height: 0pt;"></td>
<td style="border: 1px solid #000000; width: 140px; text-align: center; line-height: 0pt;"></td>
<td style="border: 1px solid #000000; width: 140px; text-align: center; line-height: 0pt;"></td>
</tr>

And place it above you existing code directly under the <tbody>

Now you need to copy and paste the following code between each of the 0pt;"></td> tags:

<span style="font-family: arial; color: #000000; font-size: 10.5pt; text-transform: capitalize;"><em>wealthy affiliate</em></span>

Preview and you should see this, although again you will probably only see the alt text:

If you're happy with it, save as draft.
