Fixed table headers

When there is a higher number of columns and rows, it's pretty hard to know what column you're looking at unless it's in the top few items in the table.

Fixed header with new sticky hash column in this tool. I found this tool instead and have been using it since 2 years. It has frequent updates as well. It has really good UI. https://github.com/kritish-dhaubanjar/dynamodb-dashboard
