Does not work when datatable contains hidden columns

[mklerx]

Let me start to say I really appreciate this project.
I have one problem that I am trying to fix, but I think this will affect other users as well.

I have a hidden column in my column definitions (bVisible: false). The first one actually (column ID 0). Datatables does not create a for a hidden column. But your logic to detect which column has the expand button uses a jQuery call:

var headerElements = $('thead th', this.tableElement);

Which does not take the hidden columns into account.

This can be solved by changing this line to:

var headerElements = this.tableElement.fnSettings().aoColumns;

and an

element = element.nTh;

after the _each on line 164. This fixes the incorrect expand column.

But then the detection of which columns should be hidden and shown still fails and the column to the right of the one that should be hidden is hidden (because of the difference between th:eq(0) and column with ID 0.

Do you agree it would be best to use fnSettings().aoColumns instead of the (incomplete) $('th') in your code?

Yes, it is better to use fnSettings().aoColumns. It should be fixed now. Make sure you define data-class="expand" on a non-hidden column th.
