Thank you for this information. I will try to learn more about this. Here, do you prefer sliding row by row or slide the whole paragraph? I think it would be better if I try and get back to you. If a table is too large (or a snippet with multiple columns), when we move the cursor to the edge of any of the rows, whole table (snippet) should slide.

Of course I will. Thank you Hashini
