SSpread.AllowCellOverflow Property
Set whether to display in the adjacent cell when the character string set in the cell is larger than the width of the cell.
Specify $TRUE if it is displayed outside, and $FALSE otherwise. The initial value is $FALSE.
If the cell is left-aligned, it extends to the right cell, and if it is right-aligned, it extends to the left cell. If it is centered, it will stick out to the cells on both sides.
If a value is set in the cell next to the cell, the value in that cell is displayed with priority, so it does not extend.
