Easier adding of rows and columns
A problem with Excel is when you add a row by selecting the adjacent row, it takes on the formatting of that row, when you don't always want it to. A much better way is to add a row in a similar way to a table in Word, where a '+' sign appears if you hover at the end of the row. In a word table you can also add a row above or below the one selected, which is much more flexible. I suggest importing these functions into Excel.
