Delta Column in Looker Table Chart

[Shafeeq_Rahaman]

Hi,

I am looking to add a delta column in my table to each of the measure, i.e., comparison of yesterday vs day before (day over day percent change)

Could someone let me know how can I achieve this?
Ex: Impression (column name) should show yesterday value and a new column beside it to have the percentage difference of yesterday vs day before

Would like to have a delta column for each measure i.e., impressions, clicks
