hides or shows the column
| columnId |
$$("ssheet").hideColumn(2, true, "Sheet1");
If the columnId parameter isn't specified, the method hides the selected column.
The method can accept an array of ids as the first parameter. In this case all the columns from the range will be hidden:
// hides all the columns from the range
$$("ssheet").hideColumn([2, 5], true, "Sheet1");
