Bug description

Testing version 6.1.0rc1, pivot tables appear broken, unable to display date columns as shown in the screenshot. I’ve tried various formats and both Druid and Databricks data sources, but the issue persists in all cases.

This is a known bug. PR #38191 has a fix for this issue but it hasn't been merged yet.

The root cause is that date formatters expect Date or Number parameters, but string values are being passed instead, resulting in the "0NaN-NaN-NaN" display you're seeing.

To reply, just mention @dosu.
