I am trying to set a custom tooltip to all table cells.
But it works only for the first column.

My code looks like this:

Tree tableTree = new Tree(this, SWT.BORDER | SWT.V_SCROLL);
dependencyTreeViewer = new TreeViewer(tableTree);

TreeViewerColumn column1viewer = new TreeViewerColumn(dependencyTreeViewer, SWT.LEFT);
column1viewer.setLabelProvider(new DependencyColumnLabelProvider());

TreeViewerColumn column2viewer = new TreeViewerColumn(dependencyTreeViewer, SWT.LEFT);
column2viewer.setLabelProvider(new TypeColumnLabelProvider());

dependencyTreeViewer.setContentProvider(new DependencyTreeContentProvider());
ColumnViewerToolTipSupport.enableFor(dependencyTreeViewer,To olTip.NO_RECREATE);

DependencyColumnLabelProvider and TypeColumnLabelProvider inherit from ColumnLabelProvider
I override the getToolTipText(Object element) method in the same manner in both classes but I can see tooltip only for the first column.

Is it something to do with this being a tree table and not a simple table?

any help will be much appreciated.

You need to create your tree with new Tree(this, SWT.BORDER |
SWT.V_SCROLL | SWT.FULL_SELECTION);
