<DL>
<DD>Replaces the current <code>dataVector</code> instance variable with the

  <code>columnNames</code> are the names

  mapped to column 0 in <code>newData</code>. Each row in
  <code>newData</code>
  is adjusted to match the number of columns in <code>columnNames</code>
  either by truncating the <code>Vector</code> if it is too long,
  or adding <code>null</code> values if it is too short.
