When attempting to load the plug-in on a large dataset (tested on ~1200 rows) with fixed columns (tested with 2 colums fixed), javascript is taking inordinately long to complete the process. FF9.0.1 gives repeated script warnings, and IE9 just waits, up to 2 minutes. If we remove the fixed columns, the render times drop to almost nothing.

The dataset tested has 1198 rows of 12 columns. The table is ajaxed onto the page (not that it should matter). I have also tried with a dataset of ~230 rows (same columns) which is also slower than it should be but not enough to stop the JS engine.
