I still see the namespace column in master. I only see it in workload detail views, not pod. It looks related to this line:
https://github.com/rancher/dashboard/blame/master/shell/detail/workload/index.vue#L200

In 2.9 this simple equality check works; maybe something changed in type-map/headersFor in the 2.10 timeframe such that the namespace column returned by the action in this component is no longer a reference to the same object imported as NAMESPACE_COL. One solution would be to compare keys on the header objects:

return this.$store.getters['type-map/headersFor'](this.podSchema).filter((h) => !h.name || h.name !== NAMESPACE_COL.name)

Happy to split this off into a separate issue if that makes more sense to you @aalves08 . The styling change in this PR LGTM

@mantis-toboggan-md thanks for catching that part of the NAMESPACE col. It's now fixed on this PR
