Resize the column of a table to fill all the available space

Question

I have this table in Eclipse SWT, with 5 columns. I resize the window and together with that the whole table but the columns don't get resized to fill all the available space.

Is there a layout method I can use in order to make a column resize itself to fill all the available space? I found some code that makes the columns resize when the client space has been resized but that seems like a small hack to me.

There surely must be a decent elegant way of doing this by using the layout itself.

This might come in handy:

Composite tableComposite = new Composite(parent, SWT.NONE);
TableViewer xslTable = new TableViewer(tableComposite, SWT.SINGLE | SWT.FULL_SELECTION | SWT.H_SCROLL | SWT.V_SCROLL);
xslTable.getTable().setLinesVisible(true);
xslTable.getTable().setHeaderVisible(true);
TableViewerColumn stylesheetColumn = new TableViewerColumn(xslTable, SWT.NONE);
stylesheetColumn.getColumn().setText(COLUMN_NAMES[0]);
stylesheetColumn.getColumn().setResizable(false);
TableViewerColumn conceptColumn = new TableViewerColumn(xslTable, SWT.NONE);
conceptColumn.getColumn().setText(COLUMN_NAMES[1]);
conceptColumn.getColumn().setResizable(false);
TableColumnLayout tableLayout = new TableColumnLayout();
tableComposite.setLayout(tableLayout);

layoutTableColumns();

The layoutTableColumns method

  /**
   * Resize table columns so the concept column is packed and the stylesheet column takes the rest of the space
   */
  private void layoutTableColumns()
  {
    // Resize the columns to fit the contents
    conceptColumn.getColumn().pack();
    stylesheetColumn.getColumn().pack();
    // Use the packed widths as the minimum widths
    int stylesheetWidth = stylesheetColumn.getColumn().getWidth();
    int conceptWidth = conceptColumn.getColumn().getWidth();
    // Set stylesheet column to fill 100% and concept column to fit 0%, but with their packed widths as minimums
    tableLayout.setColumnData(stylesheetColumn.getColumn(), new ColumnWeightData(100, stylesheetWidth));
    tableLayout.setColumnData(conceptColumn.getColumn(), new ColumnWeightData(0, conceptWidth));
  }
