code: public Object getColumnValue(int iColumnIndex, int iEditMode)
      {
          Convert fieldInfo = this.getFieldInfo(iColumnIndex);
          if (fieldInfo != null)
              return fieldInfo.getString();
          return Constants.BLANK;
      }
docs: Get the value of the field at the column.
  This is NOT a TableModel override, this is my method.
  @param iColumnIndex The column.
  @return The string at this location.
