I've put this here because I'm less likely to break anything

<table> - this starts you off
<tr> - start of a row
<td width="200"> <b> Group A </b> </td> <td width="200">etc</td>
The width="200" is optional and I just altered it till it looked right. All cells in the same column keep this width. Without it the columns bunch up and take the longest text to determine the witdh. An alternative is "25%" which would split the table into quarters - but you have to specify a table size for that to make sense.
You need a <td width="200"> for each column if you are using it.
The "" are not optional (at least I don't think they are). Each <td> must have a closing </td>
</tr> this ends the first row
<tr> start a new row <td> </td> <td> </td> </tr>
</table> when finished
If the table is to be the last thing in the post then I suggest writing some text in anyway to make sure it previews properly. It can be deleted in the Blog Entry part when you are happy. If you don't check then it can mess up the following posts if you've missed a closing tag off - I should know, I've done it twice
.
Always make sure there's a closing tag for each opening tag. The most common exceptions are <p> and <br>
And make sure that each <tr></tr> has the same number of <td></td> in it otherwise things go wrong.
There are other things you can do like make a cell go over more than one row or column, changing colours, lines around the cells and the info is in the link where you add blog and journal entries.
