Gmail converts this:
<td style=â€œheight: 20px;â€>td>
<td style=â€œmin-height: 20px;â€>td>
The min-height property does not have the same effect as the â€œheightâ€ property in TDs. This seems to have a universal effect in all browsers. By adding a or a
inside the empty cell, it resolves the problem.
<td style=â€œmin-height: 20px;â€> td>
