a particular cell in excel
THE title bar, menu bar, quick access tool bar, as

about them again, but there are features here that we have not come across
those are the one we will treat now: these are as follows:
·

the formula bar is blank and
horizontally placed under the quick access tool bar. It displays the contents
of an active cell. It is also used to enter formula.
