title: gwt celltable: Possible to only make some cells in a column editable?
body: <p>I'm using GWT 2.4.  When using a CellTable, I've seen its possible to add a column in which all of the cells are editable ...</p>
  
  <pre><code>final TextInputCell nameCell = new TextInputCell();
  Column&lt;Contact, String&gt; nameColumn = new Column&lt;Contact, String&gt;(nameCell) {
    @Override
    public String getValue(Contact object) {
      return object.name;
    }
  };
  table.addColumn(nameColumn, "Name");
  </code></pre>
  
  <p>but what if I don't want every cell in the column to be editable, only specific ones, based on properties in my "Contact" object?  How would I set this up?  Thanks, - Dave</p>
