empty fields in a table

why does Splunk display empty fields in the table even though there are values there

Cells in a table tend to be empty because either 1) the field has no value in the event; or 2) the event has no field by that name.
Run the search in Verbose Mode then look in the Events tab to see if the fields are indeed present and have values. Pay close attention to the spelling and capitalization of field names as Splunk cares about both. "status" is not the same as "Status", for example.

Pro tip: Add a default clause to your case functions to catch unexpected values. Something like eval description = case(status==200, "OK", ..., 1==1, "unknown").

Yes, you're right about mode. I tried Verbose mode, and it works as expected. Thank you

But I face another issue: I have following a splunk query

source="maillog.log" host="mail_server" sourcetype="mail" | rex "(?\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3})"

When I use top command

source="maillog.log" host="mail_server" sourcetype="mail" | rex "(?\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3})" | top ip

it shows well. But when using table command it shows again field with null.

source="maillog.log" host="mail_server" sourcetype="mail" | rex "(?\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3})" | table _time ip

I use Verbose mode and there are values in ip field.

I'm also having this problem, already in verbose mode but I had to go into "XX more fields" to add these to my initial query. Am I better off attempting this as a dashboard or getting those fields automatically added to the search? @richgalloway

If you're having a similar problem, but this solution doesn't help then you have a different problem and should post a new question.
