e.g. this when in table mode in results for Curve8.

Reverting to v2.19.0 corrects the issue

Hey @hipitihop,

A while back, I changed the signature of simple-v-table's column-header-render function. I should have known this might be a breaking change. Only simple-v-table is affected, not v-table.

When users pass in their own function for the :column-header-render prop, it needs to have the new signature: a single map of keyword arguments, not positional arguments.

The changes above should be all we need to fix our prod repos.
