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

…1296)

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.
