Transform Table header using regex

Hi Everyone.
anyone have any idea about regex to replace the first letter table header columns with the capital letter in Grafana Dashboard?
like if JSON is like below
so it will display ‘name’ in table column but I want it to display as ‘Name’ using
grafana function filter by name.
grafana version is 8.0 and linux
Datasource is OpenSearch
Query using rawData with 500.
