revert: Revert "feat: Table rendering support for databars (#1212)"

[mofojed]

This reverts commit a17cc0e.

• Noticed an issue when changing filters on a table with a string column which would cause null to be flashed in. Caused by the databar changes. We don't need the databars for this release so just reverting that change for now.
