When a data row has a cell with a long string, this view (View Underlying Data) word-wraps the string expanding the row to fit all the text into the cell.  This means that tables that have rows with long strings only display one or two rows.

The display of rows should be limited to one line and 20 characters per cell.  That way the user can see multiple rows in the underlying table.  This makes the "View Underlying Data" view more useful. 

Long strings could be displayed in ToolTips when the user hovers over the appropriate cell.  And, of course, full cell contents would be viewable in the "Export Table" function.
