I forgot to write that you need to call following function to activate DD on table, example :
setTableColMova ble("my_table_i d","one_html_fi eld",[0,1,2,3]);

this call initiate table DD and also specify an HTML field (hidden by example) to store reordered columns numbers list. So initial column numbers are to be passed into last param (here [0,1,2,3]) in setTableColMova ble call

hope it's clear...

Here is a custom version, which highlight selected column to move, show insertion point as a vertical line (left cells border style update) during column drag (like firefox tab drag&drop) and keep original table styles. Seems to work on my stuff, hope it will help ;)
