Describe two ways in which columns and rows can be inserted and deleted

What will be an ideal response?

On the Home tab, in the Cells group, click the Insert arrow, and then click Insert Sheet Rows or Insert Sheet Columns. An alternative way to insert a row or column is to right-click on the row or column label and select Insert from the shortcut menu. The same methods can be used to delete rows or columns by selecting Delete instead of Insert from the shortcut menu.
