Hi, Wylie. Do yo mean removing the whole line on line 3 or just the pipe |?

I am afraid I don't really understand how var\_set and var works according to the documentation below.

> **[Canvas function reference | Kibana Guide \[7.12\] | Elastic](https://www.elastic.co/guide/en/kibana/7.12/canvas-function-reference.html#var_set_fn)**

I also found examples of them here - [How to create a new line on a kibana canvas table - #6 by wylie](https://discuss.elastic.co/t/how-to-create-a-new-line-on-a-kibana-canvas-table/248179/6) .
