3. Choose a table style.
Note: click New Table Style to create your own table style or right click a table style and click Duplicate to create a new table style that is similar to an existing one. Modifying a custom table style affects all tables in a workbook that use that table style. This can save a lot of time.

Result. This is another way to insert a table.
To convert this table back to a normal range of cells (and keep the formatting), execute the following steps.
5. First, select a cell inside the table. Next, on the Design tab, in the Tools group, click Convert to Range.
Result. A nicely formatted range of cells.
Note: to remove the table style, select the range of cells, on the Home tab, in the Styles group, click Normal..
