TreeDataGrid Header Template

[nasterhe]

If the ColumnHeader text is too long and the cell content is short, in DataGrid, I can set multiple TextBlocks to the HeaderTemplate, and the height of the entire header of the DataGrid will be automatically adjusted. How can I achieve a similar function in HierarchicalExpanderColumn mode in TreeDataGrid?

I known how to do it.
It also uses the same method as DataGrid, using HeaderTemplate.
