This demo uses the jQuery package to realize the drag-and-drop function of table column width and realize the re-layout when the page is reset. Use jQuery to facilitate function calls. After adding an id to the table to be processed, you can directly call $("#id").movedTh() to facilitate the implementation and modify the compatibility of firfox.
The code is as follows:
