Hoping for some help here...  
I have created a lens data table visualisation where I have a number of filters defining the rows in the table and a number of filters summing various criteria for the columns.  
I want to add another column but I want this format to be a % based on a filter criteria / sum of total of another field in that grouping.

I can't seem to be able to do this in latest version of Kibana, and I can't use TSVB because the terms in which I want to group the data by is based on a collection of different values.

e.g.

| | Visited | Purchased | % Purchased |
| --- | --- | --- | --- |
| CustomerGroupX | 10 | 1 | 10.0% |
| CustomerGroupY | 20 | 15 | 75.0% |
| CustomerGroupZ | 50 | 34 | 68.0% |

Lens formula should you allow to do this by using the `overall_sum` function (similar to the "percent of total" example here: [Create visualizations with Lens | Kibana Guide [8.2] | Elastic](https://www.elastic.co/guide/en/kibana/current/lens.html#lens-formulas) )

Hey...thank you for the reply. Unless I'm missing something glaringly obvious in the configuration of the lens I can't seem to get this to work.  
It seems to add the % calculation to each column in the table. I only want to add it as an individual column.

For example

| What I want | | | | |
| --- | --- | --- | --- | --- |
| | Visited | Purchased | Converted | |
| CustomerGroupX | 10 | 1 | 10.0% | |
| CustomerGroupY | 20 | 15 | 75.0% | |
| CustomerGroupZ | 50 | 34 | 68.0% | |
| | | | | |
| What I get | | | | |
| | Visited | | Purchased | Converted |
| CustomerGroupX | 10 | x.xx% | 1 | y.y% |
| CustomerGroupY | 20 | x.x% | 15 | y.y% |
| CustomerGroupZ | 50 | x.x% | 34 | y.y% |

I'm guessing at your configuration but try removing the "Columns" configuration entirely (this is like a pivot table so it'll repeat the metrics for each pivot which it sounds like you don't want)....then, name each metric "Visited" "Purchased" "Converted" - you can write a filter for each metric under advanced options if you need it.
