Auto Resizing NatTable in Eclipse RCP Application

I am trying to auto resize my NatTable. I have few things :

1) My NatTable consists of only one column. 2) I am hiding NatTable occasionally. 3) The Part Control surrounding NatTable auto resizes on mouse drag. NatTable should also fit the size. 4) I have custom cell painters for NatTable Cells.

I tried with my bodyDataLayer(Which is based on GlazedListsDataProvider) :

    bodyDataLayer.setDefaultRowHeight(35); 
    bodyDataLayer.setColumnWidthByPosition(0, 100);
    bodyDataLayer.setColumnPercentageSizing(true);

But nattable does not show up at all. If I double click the invisible rows, I get required row. But natTable itself does not appear. NatTable shows up only if bodyDataLayer.setDefaultColumnWidth(SOME_VALUE); Only default column width works.

I tried to add a Paint Listener to NatTable to initialize auto resize commands as suggested on Official Documentation. But it has no effect at all.

I tried to add 

   natTable.setLayerPainter(
            new NatGridLayerPainter(natTable, SOME_VALUE));

with auto resizing of columns by position.But it also renders nothing. I am wondering how to resize my NatTable?

Typically DataLayer#setColumnPercentageSizing(true)should be sufficient for percentage sizing.

I can only assume that hiding NatTable occasionally has a negative effect, because that might lead to miscalculation of the percentage values. 100% of 0 is still 0.

Are you calling NatTable#setVisible(false) to hide the NatTable? In that case try to execute the following lines of code

natTable.doCommand(new ClientAreaResizeCommand(natTable));
natTable.redraw();

If that fixes your issue, please open a ticket and report that issue. In that case it seems we need to add a listener for SWT.Show or override setVisible() to execute these lines of code on visibility changes.
