BLNestedTableView

A nested UITableView

It has two levels' tableView:

• the main tableView is the top level view.
• and many nestedTableViews are the second level view.

When expand a cell, it'll insert a cell after the clicked cell. For example, when you click cell at [section:0 row:0], then a cell will insert after it, so the NSIndexPath will be [section:0 row:1], but this won't effect the original cell of [section:0 row:1].

Clone it & run.
