Creating Grouped Worksheets

Hi,
I am using a file that has multiple tabs. When I create the columns and formats in Sheet 1, is there a way I can have this grouped to all other tabs? I created the first wkst, and copied it to all the other tabs (timely, but worked) however, everytime I make a change to wkst 1 (example adding columns or rows), I'd like to be able to have it automatically populate into the other sheets. Many years ago I seem to remember some way of grouping worksheets. Also, if the formatting and set up can be duplicated, is it possible to have the formulas from worksheet 1 populate to the other tabs?
I am trying to be able to set this worksheet up only once to avoid going in to each tab everytime I make a change in formats or formulas.
Thanks for any help you could provide.

1) Click on the sheet1 to activate it
2) Shift-click on the last sheet. This groups all the sheets and "selects" them all at the same time
3) Make your formatting edits on sheet1, they will be happening in all sheets at the same time

When done:
4) Right-click on the sheet tabs and select UNGROUP sheets.

Before making changes to one sheet, group all sheets together
