Problem

A table doesn't sort if the column with dates has an empty value in one row.

Environment

Confluence (DC)

Steps to Reproduce

1. Create a page
2. Create a table with 2-3 columns
3. Fill one column with dates by skipping one row. or you may use this storage format.
4. Publish the page
5. Try to sort the table.

Expected Results

Columns are sorted asc and desc

Actual Results

None happens, columns stay in their current order. Or sometimes it's sorting once and gets broken for the next clicks/

Workaround

There is no workaround to fix this issue. The only thing that might fix is using string values instead of a date or filling all the rows in the date column.
