You can add rows and columns to an Excel table, or remove them from an Excel table
without deleting the cells’ contents, by dragging the resize handle at the Excel table’s
lower-right corner. If your Excel table’s headers contain a recognizable series of values
(such as Region1 , Region2 , and Region3 ), and you drag the resize handle to create a fourth
column, Excel creates the column with the label Region4 —the next value in the series.
Excel tables often contain data you can summarize by calculating a sum or average, or
by finding the maximum or minimum value in a column. To summarize one or more
columns of data, you can add a Total row to your Excel table.
When you add the Total row, Excel creates a formula that summarizes the values in the
rightmost Excel table column. To change that summary operation, or to add a summary
operation to any other cell in the Total row, click the cell, click the arrow that appears,
and then click the summary operation you want to apply. Clicking the More Functions
menu item displays the Insert Function dialog box, from which you can select any of the
functions available in Excel.
Much as it does when you create a new worksheet, Excel gives your Excel tables
generic names such as Table1 and Table2 . You can change an Excel table’s name to
something easier to recognize by clicking any cell in the table, clicking the Design
contextual tab, and then, in the Properties group, editing the value in the Table Name
box. Changing an Excel table name might not seem important, but it helps make
formulas that summarize Excel table data much easier to understand. You should make
a habit of renaming your Excel tables so you can recognize the data they contain.
