I've just got Numbers, which I've found to be very good. But, after watching the tutorials and reading the Help pages, there are 2 things I'd love to be able to do but can't:- 1. Add a percentage onto a SUM of a column. For instance, I have an invoice, with a column of sales totals, and a VAT row. I'd like to add up the column, THEN automatically add a VAT amount to the total of those rows and display the overall total in the total cell. 2. I'd like to be able to specify the entire length of a group of cells in a table, and then evenly space the cells to take up that space. For instance, I want a row of cells that has a total length of 20cm from top to bottom, and want as many cells as possible to fill the 20cm equally. Can anyone help please? Thanks.
