Table values can be used in Jira Automation and accessed via smart values.
To return values from one column across all rows:
{{#issue.properties.stjc-field-654.values}}{{2237}}, {{/}}
where
654 - table field ID
2237 - table column ID
To return values from one column AND one specific cell
{{#issue.properties.stjc-field-654.values.get(0)}}{{2237}}, {{/}}
where
654 - table field ID
2237 - table column ID
0 - row position (0 = first row).
