Hello,  
we have GW ignition 8.1.37 with Vision.  
I would like to know if for source filter on table we can use regular expression?

Best regards, Tadeja

No, just simple wildcards.

You can always implement the [`filterAlarm`](https://www.docs.inductiveautomation.com/docs/8.1/appendix/components/vision-components/alarming/alarm-status-table/alarm-status-table-scripting#filteralarm) extension function if you have more complicated logic than can easily be expressed in the string-based conditional.
