my 2 laboratory

In my first laboratory at economic informatics I have seen that there ar important diferences between Excel 2003 and Excel 2007 wich I thaught I know to work in. First of all I tried to find diferences between those two... there are a lot... So, I started to work on general application in Excel 2007, like deleting cells, shift cell left, shift cell up, deleting entire row, entire column, merge and center, merge across, merge cell, unmerge cell.
