Message:

why the scollbar had no effect?

Posted by hindsight on February 06, 2002 at 2:33 AM

HERE IS PART OF THE CODE,
THE TABLE OWNED MANY COLUMNS AND I WANT TO SHOW EVERY COLUMN IN ITS FITTEST SIZE AND PULL SCROLLBAR TO SHOW THOSE CAN'T BE SHOWN.
IF I USE A METHOD TO SHOW THE FIT SIZE,THE HORIZON SCROLLBAR NEVER APPEAR AND ONLY SHOW PART OF THE COLUMS.IF I DIDN'T USE THE
METHOD,IT SHOW ALL WITHOUR SCROLLBAR BUT WITHOUT WHOLE NAME OF THE COLUMN.HOW COULD I DO IT OR WHERE IS WRONG IN THE CODE?
THANX IN ADVANCE.
