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

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

## Create Tableau Table Calculations

In this tool, you can create table calculations in multiple ways, and the first approach is to right-click on the measure and select Create -> calculated Fields. For the second approach, please navigate to the Analysis Tab and select the 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 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 the Cancel button to close the window and then click OK.

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

## How to Edit Table Calculations?

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.

### Tableau Table Down Calculation

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

### Tableau Pane Down Table Calculations

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

### Tableau Table Calculations on 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 displays a few more options.

### Tableau Table across calculations

Table Cross Calculations will apply the first function for each row in a table.

### Tableau Table across then down calculations

The Table across then down will apply the first function for each row and then go to the next row.

### Tableau Table down then across

It will apply the first function for each row in a column and then go to the next column.

### Pane Down calculation

It will calculate from the first row to the end row in a Pane or group.

### Tableau Pane across then down calculation

The Pane down then down calculations will calculate from the first row to the end row in a Pane or group.

### Tableau Table Calculation on Specific Dimension

As we said before, use your own dimension to compute the calculation. Here, it applies the FIRST function for each quarter.

The FIRST function calculates each quarter and segment.

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