  <p><a href="https://www.ag-grid.com/javascript-grid-grouping/#unbalanced-groups" rel="nofollow noreferrer">This link</a> says that in order to prevent unbalanced groups, you have to change your data to replace nulls or undefineds with blank space characters.  I don't want to change my data.  I tried using a cellRenderer to display nulls and undefineds as blank characters.  This seems like an obvious solution, but my groups were still unbalanced.</p>
