There are times when pasting to the bottom of an existing large, formatted table can take a few minutes to update. There is a quicker way.
When the formatted table is selected there is a Table Design (or Design) tab visible.
On the far left-hand side the Resize Table icon allows you to easily extend the range of the formatted.
You can amend the range and add sufficient rows to handle the new data in the dialog that opens.
When you paste into an existing formatted table (rather on the end of the table) you will find it will update a lot quicker.
