Support mData property

[fkurth]

yadcf accesses column data by means of the column_number. If the dataTables option "mData" (1) is used, it may select the wrong data column.

Attached is a small patch to make it work.

Thanks , but your solution will won't work on a non mData datatable, because it seems that if you don't use mData explicitly it will be populated with column numbers , e.g for first column .mData is 0, for second .mData is 1 and so on... Anyway I did implemented the mData support and I did it for deep property reading from a data source too...
