Have a rather large workbook that was given to me to work on. Am trying to set all sheets to be formatted the same. I find that the very light blue gridline is difficult to see sometimes. I found where you can change the color of the gridline which I do like. However not only does it change that but it also changes all of the borders on the sheet which I do not want changed and now cannot change back to black (unless I go back to the advanced options). Does anyone know how I can change ONLY the gridlines and not the borders? This would be on a Windows 7 machine using Excel 2007. Any help - much appreciated
