# Rows & Columns Calculation

Row / Column Calculation is a feature that many Ninja Tables plugin users would like to implement in their tables.

• You may perform this kind of calculation by just following a few easy steps.

• Follow this simple guide to discover how to calculate data in table rows and columns.

## Row Calculation #

• For demonstration purposes, a table has been created using test data.

• This table basically contains 3 number columns named Number one, Number Two & Number Three. And another column named Result displays the calculated results of all the number columns. Look at the example below to get a clear idea –

• If you want to calculate the sum of the three number columns and show it in the Result column.

• Firstly navigate to the Table Configuration tab and click on the Edit icon on the right side of the column bar.

• In the Transform value option, you need to add a shortcode to find the sum of the 1st three columns. Ninja Tables has a feature to Enable Excel Formula support for Transform Value, click on this option to get the sum’s formula.
• This is a basic single-line shortcode: ` =SUM({{Column 1}}+{{Column 2}}+{{Column 3}}) `. Inside the curly brackets place the Shortcode Value off all three columns. To learn more about this feature, read this documentation.

• So the final code would look like this: `=SUM( {{row.numberone}} + {{row.numbertwo}} + {{row.numberthree}})`. Then click on the Update button to save the code. In the preview mode, the Result column of the table will now display the sum of the 1st three number columns. Like the example given below –

## Column Calculation #

• Regarding column calculation, a specific code can be used to implement this. First, go to this GitHub link to get the JS code. Copy the code. Now go to the Custom CSS/JS tab & click on the Custom Javascript button. Paste the code that you copied and hit the save button.

• If you wish to calculate the total sum of all the numbers in the 1st column, you need to give the Column key of that specific column, on the first line of the code, which is `var myClasses=""` If you want to show the results of one single column, you need to put the key to that column only. If you want to apply calculations to multiple columns, put their columns key by using commas in between each column key.
