Sometimes we need gridlines, and sometimes we don't, depending on the actual business needs. Perhaps because Excel typesetting is convenient, so sometimes you want to use the Excel document in Word, then you do not need the grid line.
The grid line settings in Excel are managed in the form of a table (Sheet), which means that you can have one table display gridlines and the other table not, which is not conflicting.
Ways to get rid of grid lines:
1, remove the table line in the Editing window, click Options on the Tools menu, and then select View to find gridlines to invalidate the grid line.
2. Remove undefined form line when printing
There are times when this happens: you are not defined in the editing of the table line (seen in the editing window is also a light gray form line), usually in the printing will not print out, but sometimes do not listen to the print out, especially some so-called "computer" The Excel table edited in VCD is more like this. To get rid of these table lines, simply deselect gridlines by clicking the file, Page setup, worksheet menu, and clicking the selection box to the left of grid lines.
