Cannot change visibility of a column

yshtil

I tried to follow the documentation but the column stays visible, what am I doing wrong:

table.column( 0 ).visible( false );

I debugged it in Chrome and the statement table.column( 0 ).visible() always returns true after table.column( 0 ).visible( false )

here it works, without a test case from you, it's hard to tell what's wrong
