Feature Request: inline edit for mtx-grid

[someshjagtap]

I would like to say thank you so much for your great and wonderful contribution to building this theme or library publically.
It is really helpful for understanding the navigation, routing, Authority, and widgets which you have provided pretty coolly.
We have used this theme in most of our projects,
and we feel very comfortable with this but still good to have the following things in library -

Inline Edit for Table Grid.
Text Overlay for Table Grid Cell
hide and show Columns based on Authority and Permissions.
