Column hidding

itassets

I've a table with many columns. Columns are colgrouped by months and the column's names are repeted in each colgroup.

..... ..... .....

January				December
Week 1
Week 4
...

The user has to hide week(n). i.e. all columns Week 1, col week 1 from January to December.

I'm trying to hide columns this way but not working:

var table = $('#tabla').DataTable();
var columna = table.column('#week1');
columna.visible(false);

table.column throws Uncaught typeError: undefinied is not a function. The table is well visualized, meaning, there is data in its cells and is properly displayed.

I've try many approaches to hide columns but with no success. I need some help on this.

Thanks,
