1. Is it possible to select which row or column formatting it should follow when a new row/column is inserted to the table?

For example
Col1 --- Col2 --- Col3

If you insert a new column
Col1 --- Col2 --- NewCol --- Col3

NewCol copies the formatting of Col3, but I want Col2's.
How?

2. When I drag and drop the table column, Word automatically adjust the width of the column to match the right side of the column. It is annoying. I want it to keep the original width. How to do?

For example
Col1 --- Col2 [width 2cm] --- Col3 --- Col4 [width 6cm]

Then I dragged and dropped Col2
Col1 --- Col3 --- Col2 [width 6cm] --- Col4 [width 6cm]

I don't want to change the width. I want to keep it 2cm after I moved Col2.
How?

Any efficient workaround is appreciated.

Thank you very much.
