Tableau Table Calculations are a special type of calculated field. Unlike regular calculated fields, these are based on the data that is currently visualized in a report. This article shows how to create table calculations and how to use their properties.

For these Tableau Table calculations demo, we use the Global Super Store Excel Worksheet. Before creating them, let me create a simple report.

## Create Tableau Table Calculations

In this Bi tool, you can create table calculations 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.

Please refer to Tab Report, calculated field, and Connecting to the Excel Files in Tableau.

Selecting the option will open the following window. Here, we renamed the default name as Cal. The below statement will find the First records in this data. Here, you can click OK to close this window.

Or you can click the Default hyperlink (marked below) to alter the default settings, and it opens the following window.

Use this window to change the Tableau table Calculation field, Levels, etc. I am not a fan of making any modifications using this window. However, you can do it. Let me click Cancel button to close the window, and then click OK button.

Let me drag this first Cal to the Measures shelf in the design area.

### Edit

Altering or editing the Tableau Table Calculations is very simple. Click the down arrow, and select Compute using to change the computing options.

Let us see the list of available options. For this, let me select the Edit Table Calculation option from Measure Values.

It will open a new window called Edit calculation.

#### Table Down Calculation

Tableau Table Down Calculations will start calculating from the first row to the end row in a complete table.

#### Pane Down

The Tableau Pane Down will calculate from the first row to the end row in a Pane or group. From the below screenshot, the First is applying for each quarter.

#### Specific Dimensions

You can use any dimensional column to compute the Table calculation. Here, it applies the FIRST function for each year.

You can also change the Sort order, and sorting column

Let me add Segments filed to the Columns shelf to explore a few more options. As you can see, it is displaying a few more options.

#### Table across

The FIRST function calculates for each quarter and segment.

Here, the FIRST function applies for each year and segment.
