Pages with lots of TML tables that are styled using something similar like

%TABLE{tableborder="0" cellpadding="1" align="center" valign="middle" databg="#D8DFF1, #E8EEF5" datacolor="#244E7E, #244E7E" headerbg="#C1D2EC" headercolor="#123D71",}%

will impact performance for no good reason. Profiling shows it to be related to the code adding inline css to the head of the html page.

Profiling shows that _writeStyleToHEAD is responsible for this performance problem:

Switching off all %TABLE macros using

   * Set TABLE = 

mitigates the problem for a single page. For now it seems preferable not to customize a table's look and feel using TablePlugin and only make use of it for processing table data like sorting, things that are not css related.
