Generate complex tables in Foswiki using TML

I'm trying to include content of query within table. However, I'm not sure what I'm doing wrong:

   * Set Col1 = %TREE{web="MyWeb1/Basic" excludetopic="Web*" levelprefix="   " startlevel="1" stoplevel="2"}%
   * Set Col2 = %TREE{web="MyWeb1/Configuration" excludetopic="Web*|Chart" levelprefix="   " startlevel="1" stoplevel="2"}%
   * Set Col3 = %TREE{web="MyWeb1/Advanced" excludetopic="Web*" levelprefix="   " startlevel="1" stoplevel="1"}%
   * Set Col4 = %TREE{web="MyWeb1/Tools" excludetopic="Web*" levelprefix="   " startlevel="1" stoplevel="1"}%

%TABLE{cellborder="0" cellspacing="20" columnwidths="24%,24%,24%,24%"}%
| *---++ Basics:* | *---++ Controllers:* | *---++ Advanced:* |  *---++ Tools:* |
| %Col1% | %Col2% | %Col3% | %Col4% |

I have a few suggestions about what will work better:

The Foswiki syntax for headings ("---++") only works when that is at the beginning of the line, so it won't work for table headers. Try using this instead: *<h2>Basics:</h2>* .
Foswiki syntax for tables is fairly easily broken by return characters and "bars" ("|") within cells. In the case where you want to put bulleted lists within cells, you'll get better results using html tabs to define your table. E.g.:
```
<table><tr><td> %Col1% </td><td> %Col2% </td> <td> %Col3% </td><td> %Col4% </td> 
```
