Hi all!

I'm a bit new with SWT/JFace and I am having problems displaying table
- I would appreciate if someone could help me out.

As mentioned, I'm trying to use TableLayout to display table data:

Group group=new Group(this,SWT.SHADOW_ETCHED_IN);
group.setText("table");
group.setBounds(0,0,400,400);

final TableViewer viewer=new
TableViewer(group,SWT.BORDER|SWT.FULL_SELECTION);
TableLayout layout=new TableLayout();
layout.addColumnData(new ColumnWeightData(33,true));
layout.addColumnData(new ColumnWeightData(33,true));
layout.addColumnData(new ColumnWeightData(33,true));
viewer.getTable().setLayout(layout);
viewer.getTable().setLinesVisible(true);
viewer.getTable().setHeaderVisible(true);

// Set up the table layout
TableColumn column1 = new TableColumn(viewer.getTable(), SWT.CENTER);
TableColumn column2 = new TableColumn(viewer.getTable(), SWT.CENTER);
TableColumn column3 = new TableColumn(viewer.getTable(), SWT.CENTER);
TableItem item = new TableItem(viewer.getTable(), SWT.NONE);
item.setText( new String[] { "column 1",
"column 2",
"column 3" } );
item = new TableItem(viewer.getTable(), SWT.NONE);
item.setText( new String[] { "a", "b", "c" } );

Now the Group gets displayed, but the table inside it doesn't, all I
see is an empty space. I think I'm missing out something very basic -
could you please help me out?

Thank you in advance & happy coding!

Anyone? Please?

I just want to display a table using JFace... I have a component that
is displayed (Group) and I want a table inside it.

I would be grateful for any hints, I am out of ideas. :(

Actually, no - what made the difference was a few lines just before
creating the TableViewer:

GridLayout gl=new GridLayout(4,false);
group.setLayout(gl);

Grrrrr... :(

This helped:
group.pack();

(added at the end of the posted code)
