Feature request: Range Selection and Copy Paste

[cubode]

Hello! Very nice library congrats! I really believe this table could become the standard with your capability to add dynamically columns and rows that many others lag, I would have some features to propose to make it shine over the competitors.

Range Selection: Being able to select rows, columns or ranges (squares of rows/colums) and copy paste them.

Do you have any schedule time to do releases? maybe we could also contact to do pull requests and help you?

Cheers!
