Adding support for onCreateItemViewHolder to create multiple type of viewholder base on row and column

I understand that viewing csv file and supporting dragging required every table cells are the same but it would be great if AdaptiveTableLayout can support multiple type of viewholder in readonly mode. That will make displaying multiple type of data (for each column) with different layouts much more easy.

Start by tracing AdaptiveTableLayout's readonly view-holder creation and the proposed onCreateItemViewHolder entry point, then inspect how row and column data are currently bound. Done means readonly tables can choose different view-holder layouts for different data types or positions while preserving existing table behavior.
