Example:

If I have text typed in and have a format Shape, say a circle, over the text
in column "C". And I delete column "B" the text will move according to the
deleted column but the Shape will not move with it.

If I insert a column in front of column "C" that has the text and shape,
both text & shape will move together.

Why will the Shape not move with the text when deleting columns but
inserting columns it will?
