There are a few ways to create pivot tables in Excel. The easiest way is to use the pivot table wizard. To do this, select the data you want to use for your pivot table and then go to the Insert tab and select PivotTable. The wizard will then walk you through the steps of creating your pivot table.
Another way to create a pivot table is to use the pivot table toolbar. To do this, select the data you want to use for your pivot table and then go to the Data tab and select PivotTable. The toolbar will then open and you can create your pivot table from there.
Finally, you can also create a pivot table by using the Excel formulas. To do this, you first need to create a table of data with the headers you want in your pivot table. Then, you need to create a pivot table formula that will sum up the data in the table. You can find a tutorial on how to do this on the Excel website.
