Java Tutorial » SWT » Table Editor 
17. 54. 1. Using TableEditor
  1. TableEditor derives from ControlEditor.
  2. TableEditor belongs to a cell.
  3. Use the setters for row and column to set the cell, like this:
TableEditor editor = new TableEditor(myTable);
editor.setEditor(myControl);
editor.setItem(myItem);
editor.setColumn(myColumn);

You can also use TableEditor's new setEditor() method that takes three parameters-an editor, an item, and a column-to set everything in one call, like this:

TableEditor editor = new TableEditor(myTable);
editor.setEditor(myControl, myItem, myColumn);
