Reordering-Columns
When this style is set, the user can change the order of the columns simply by dragging a column to its new position. No additional programming is needed because only the appearance is affected and the program still receives column information as if they were in their original positions.
This style has effect only in conjunction with the 
Table-View style. 
 
Example - Define a tree table view with 3 reordable columns
... screen section. ...   03 screen-1-tv-1 Tree-View      line 2.7      column 3.4      size 20.8 cells       lines 29.1 cells       height-in-cells      color 144      id 2      table-view      column-headings      tiled-headings      reordering-columns      cenered-headings      display-columns (1, 10, 15)      .  |
