title: How to build text trimming cell for GWT DataGrid
body: <p>I'm looking for examples for building a text-trimming cell for GWT DataGrid.
  I want the cell to have fixed width and height, and if text is longer - ellipsis (...) will appear. The complete text will appear on editing / on tool tip.</p>
  
  <p>In my current DataGrid, the text is automatically wrapped and the row height grows. I want to avoid that and to keep fixed row height.</p>
  
  <p>Can someone help?
  Thanks</p>
