When I try to resize the width of columns in Numbers, they snap to some automatic setting I'm unaware of. Either too far apart or too close together.

When I move column to the right, it will automatically shoot over too far, leaving too much space and taking other columns with it off the screen.

When I drag a column left, the opposite happens. All the columns will move, not just one, and they will scrunch up against each other.

So it's all or nothing. Never stopping where I adjust the column.

Why is it so hard to move columns manually the width I want? Why do all the columns move after I've tried to drag only one of them?
