Add Custom Column to Table

This guide explains how to add a custom column to an existing table in the dashboard. A custom column is a calculated column defined with a formula that uses other columns (e.g. [Clicks]/[Impressions]). Custom columns are available in both the table view and any chart that uses the same visualization data (e.g. when you switch the same block to a line or bar chart). Use it when you want metrics like CTR, CPA, ROAS, or any expression built from existing numeric columns without changing the data source.

Steps to Add Custom Column:

1. Open visualization settings

   • Click the Settings (gear) icon on the table block.

   • In the right-hand panel, select the Chart tab.

   

   • Scroll below to the Custom Columns section.

   
2. Add a new column

   • Click Add Custom Column.

   • From the Available columns click a column to insert it into the formula, you can also manually type the column name in the Formula within square brackets (e.g. [clicks]).

   • You must name the formula you have generated, inside the Formula Name field, this will also appear as the column label.

   

   • Since spaces are not allowed in the formula name, if you want a space to appear in the column label, add an underscore ( ‘_’ ) between words (e.g. ‘average_cpm’ will appear as ‘Average Cpm’ on the table).
