[news.eclipse.platform.swt] TableViewer, empty table and cell selection

[paul@xxxxxxxxxx (Paul Neyman)]

Hello,

I am using a TableViewer example provided in the Articles. 
(http://www.eclipse.org/articles/Article-Table-viewer/table_viewer.html).

Is there any way to initialize TableViewer on an empty Table? Currently, 
doing so causes an AssertionFailedException in the 
StucturedViewerException, because an array of elements returned by my 
IStructuredContentProvider is null (the table is empty!)

However, removing all elements from a table later does not cause any 
trouble for TableViewer. So my current hack is to insert one dummy element 
into the Table, do tableViewer.setInput() and remove the element 
afterwards. Is there a more elegant way?

My second question: the example implementation in the article lets you 
select a row by clicking on the first cell in the row only. After that I 
can edit any cell in the selected row. How can I enable arbitrary cell 
selection and immediate activation of that cell's editor?

Thank you.
