Sorting order with a condition (column class)

lenamtl

Hi,

I'm wondering how can I achieved the following.

Sometimes the columns may have a class="hidden"

Sorting the table like this if column 0 and 1 are visible
"order": [[ 2, "asc" ],[ 0, "asc" ]],

Else if column 0 have class class="hidden" then
"order": [[ 2, "asc" ],[ 1, "asc" ]],

Thanks
