libs-gui/Headers/gnustep/gui/NSTableView.h
Pierre-Yves Rivaille 7269d0c8eb * Source/NSTableHeaderCell.m: New drawing code, support for 
highlighted cells.
* Source/NSTableHeaderView.m: support for drawing highlighted
  column, support for NSTableView mouseDownInHeaderOfTableColumn:
  and didClickTableColumn: delegate messages.
* Source/NSTableView.m: rewrite of -mouseDown method.
  rewrite of selection handling to fully support the specs
  new tableView:didClickTableColumn: and
  tableView:mouseDownInHeaderOfTableColumn delegate messages
  [NSTableView -setHighlightedTableColumn:]
  [NSTableView -highlightedTableColumn]: methods implemented.
* Headers/gnustep/gui/NSTableView.h:
  new _highlightedTableColumn ivar.
