How to insert a group within a table cell using script?

Hi @SHY.John, given that you (or someone else reading this) may need to include text frame(s) here is an implementation of @Peter Kahrel's code. For help I've included the various values at the bottom of script so you can adjust the "props" object.

This script grabs the selected page items and groups them (if more than one) and adds that group to the first insertion point of the 3rd cell of the first table in the active document. It sets the anchored object settings such that the group aligns with the top left of the cell (doesn't allow for the borders though!) and then the script adjust the width and height of the cell to match the anchored item's size. Just for learning—take what you want from it. I wrote it for myself, but you never know... it might be helpful to others.
