Well… if you get bored in work on April fool, if you want to have a little fun with your colleague who is busying with his/her Excel files, here’s a minor trick for you to play with… Cautions: Take your own risk… 🙂

Well, you may think that either the Fill Color or Border Color is set to “White” to the whole worksheet, which is not uncommon indeed.

But this is not the case… 😦 

So where the gridlines go?

Try the following:

File –> Options –> Advanced (Scroll down to middle)

Check if the Gridline color is set to “White”…

Switch it back to “Automatic” and you will see the gridline again.

So you don’t have to panic when you couldn’t see the gridlines on your Excel sheet next time.  Go check the Gridline color (and probably review your working relationship to the colleague who sent you the file).  Who is going to change that setting intentionally for no purpose? 😛
