columns (and column) undefined

tonycarreon

datatables.net 1.10.3

the following code results in an error "Object doesn't support property or method 'column'". i get essentially the same error if i try columns() instead.

for (i = 0; i < 6; i++)
tbl.column(i).visible(false);

but the following works:
for(i = 0; i < 6; i++)
tbl.fnSetColumnVis(i, false);

stupid developer (me) error...

more code:

the problem was how i declared the tbl variable.

var tbl = $("mytable").dataTable({ ... });

tbl.column(0) // this was the problem.

// but this works

var tbl = $("#mytable").DataTable();

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