There are a few ways to total a column in Excel. One way is to use the SUM function. The SUM function can be used to total a column of numbers by typing "=SUM(A1:A10)" into a cell, where A1:A10 is the range of cells you want to total. The SUM function can also be used to total a column of numbers that are in a specific range by typing "=SUM(B1:B10)" into a cell, where B1:B10 is the range of cells you want to total. Another way to total a column in Excel is to use the AutoSum function. The AutoSum function can be used to total a column of numbers by typing "=AutoSum(A1:A10)" into a cell, where A1:A10 is the range of cells you want to total.
