[news.eclipse.platform.swt] missing column headers in large tables

[chris.brown@xxxxxxx (Chris)]

I am working on an RCP editor component that displays a very large tabular 
dataset (>1000 columns) using an SWT table object. Performance is 
extremely sluggish, even when the row count is very low. A couple of 
general questions:

1) Most important: after around 500 columns or so, the column headers 
simply are not painted anymore. They just disappear (see the example code 
below).
2) Horizontal scrolling is extremely slow, regardless of column count. I 
do not see the same sluggishness for vertical scrolling (and I am even 
using a virtual table). Is this configurable?
3) Are there any other general pointers out there for improving the 
responsiveness of a Table for large column count, as far as the painting 
to the screen (i.e. double buffering, etc.)?

Thanks,
Chris
