How to extract and display in a table form?

[Manth]

I have splunk logs as given below. However, I wanted display fields in between square brackets "[ ]" in a table as given below. Please advise.

Expeted query result in a table

sqsMsgId                                                                        | snsMsgId                                                                        | requestId

dec6c564-9e1c-4d0f-8e5e-ac9dc7bdf14a  | 7d81b4cf-43c0-5bb4-8370-ef064a78da16 | d487108c-863f-5ab2-96df-4b458f97c74e

My splunk Logs

Thank you for your quick response. However, I would like to display key value fields in table where field delimiter is "|" and key-value delimiter is "=". Please advise.
