Hello,
is it possible to draw custom text on the table?
I have Table and TableViewer and if there is not data to show, I would
like to display text with such message. I'd like the message to be in
first row, but go throw the more columns or to be in a special place (eg.
in the middle of control).

Putting a Label on the Table should work, snippet:
public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell(display);
shell.setBounds(10,10,200,200);
shell.setLayout(new FillLayout());
Table table = new Table(shell, SWT.NONE);
table.setLinesVisible(true);
table.setHeaderVisible(true);
shell.open();
Label label = new Label(table, SWT.CENTER);
label.setBackground(table.getBackground());
label.setBounds (5, table.getHeaderHeight(), table.getSize().x - 2 * 5,
table.getItemHeight());
label.setText("no items here");
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}

Thank you, works fine (except the weight of the label - it it very short,
I'll have probably to hardcore the weight of the label)
