Hi All,
I'm running into problems. I need to align Columns of TableViewer,
and i'm getting some troubles using TableColumn.
After run following program, consol is printed follow,
"0 column is right-align = true"
The first column's align-property is RIGHT, but data and header's
text of first column is showed leftly!!!
How to align first column of TableViewer?
How to separate align of header-text and data in TableViewer?
Could someone help me? Thanks in advance, and excuse me for my poor
english.

private TableViewer t_viewer;
public void createPartControl(Composite parent) {
t_viewer = new TableViewer(parent, SWT.BORDER | SWT.MULTI |
SWT.V_SCROLL);
Table table = t_viewer.getTable();

This is a Windows limitation. I has been suggested that you can set the
alignment for the second column and delete the first column but I have no
idea if this works. Once the second column has become the first column,
then you won't be able to change the alignment. Someone write a snippet and
try this out ...
