Expand/Collapse Rows with fixedColumns extension

Hi,

I am trying to implement the following functionality

1) I am hiding some rows using DT_RowClass and display:none for that class
2) Using fixedColumns

The issue I am facing is, when I am trying to show hidden rows, the expanded rows do not align with the already visible rows. Here is the link to an example http://plnkr.co/edit/sNDabNpzSpRGGLbO9CBL?p=preview

Looks like datatable is cloning all the rows just for fixed columns , and when I am expanding the hidden rows, all the columns for hidden rows are displayed under the fixed columns. What is the best way to overcome this issue?

Thanks.
