Tableau Table Calculations are the special type of calculated field. Unlike regular calculated fields, table calculations in Tableau are based on the data that is currently visualized in a report. In this article, we will show you, How to create Tableau table calculations, and how to use their properties with an example.

For these Tableau Table calculations demonstration, we are going to use the data present in the Global Super Store Excel Worksheet. So, Please refer Connecting to Excel Files article in Tableau to understand the connection settings.

Before we start creating Table Calculations in Tableau, let me create a Table Report.

## Create Tableau Table Calculations

In Tableau you can create table calculation in multiple ways, and the first approach is: Right click on the measure, and select Create -> calculated Fields.

The second approach, please navigate to **Analysis** Tab and select **Create Calculated Field…** option as shown below.

Selecting the **Create ****Calculated Field…** option will open the following window. Here, we renamed the default calculation name as Cal. Below statement will find the First records in this data.

Here, you can click OK to close this window

Or you can click Default Table calculation hyperlink to alter the default settings. Clicking that link will open following window.

Use this window to change the Calculation field, Levels etc. I am not a fan of doing any modifications in this window. However, you can do it.
