Alignment group is a structured group that functions along the fixed path of any plan or ideology to induce the non aligned group to fall in the path of action.
It is the position in a cell that values appear, such as left, centre, right and values can also be made to appear closer to the top or bottom of a large cell.
Normally, default alignment for text is left. Default alignment for numbers is right. The alignment depends on the template you use to build your table.
