Arlo,
Take a look at this table. Border collapse produces the grid. Othrwise your theme css takes control.
<p>
<table style="border-collapse: collapse" bordercolor="#111111" cellpadding="2" width="300" border="1"><tbody>
<tr>
<td valign="middle" align="center" width="100"><em>m</em>
</td>
<td valign="middle" align="left"> {1:NUMERICAL:=4.55:0.0} g
</td>
</tr>
<tr>
<td valign="middle" align="center" width="100"><em>V</em>
</td>
<td valign="middle" align="left"> {1:NUMERICAL:=1.25:0.0} L
</td>
</tr>
<tr>
<td valign="middle" align="center" width="100"><em>M</em>
</td>
<td valign="middle" align="left"> {1:NUMERICAL:=111.1:0.2} g/mol
</td>
</tr>
<tr>
<td valign="middle" align="center" width="100"><em>n</em>
</td>
<td valign="middle" align="left"> {1:NUMERICAL:=0.041:0.0012} mol
</td>
</tr>
<tr>
<td valign="middle" align="center" width="100"><em>c</em><sub>før</sub>
</td>
<td valign="middle" align="left"> {1:NUMERICAL:=0.0328:0.0009} mol/L
</td>
</tr></tbody>
</table></p>
will produce
| m | {1:NUMERICAL:=4.55:0.0} g |
| V | {1:NUMERICAL:=1.25:0.0} L |
| M | {1:NUMERICAL:=111.1:0.2} g/mol |
| n | {1:NUMERICAL:=0.041:0.0012} mol |
| cfør | {1:NUMERICAL:=0.0328:0.0009} mol/L |
