Hello, I am new to Libre and trying to learn the ropes. I have created a spreadsheet and everything seemed fine until I noticed one cell had a border around it that encompassed the cell next to it, in other words row 4 columns A & B have one border around both cells. I would like a sperate border around A& B as there will be seperate data in each cell (Please see attached screen shots) in the first screen shot row 4 column A & B have a border. In screen shot 2 when I click into row 5 A & B above only have the horizontal borders. I have tried removing the border as well as re-adding, but I am unable to choose column 4A independently of 4B and vice versa. What am I doing wrong?
