The grid column has both valueAccessor and formatter properties. Other grid libraries also have this sort of configuration, but whereas other libraries pass the valueAccessor return value onto all other grid features such as formatting and grouping, SyncFusion does not. It sort of leaves me wondering what is the purpose of valueAccessor? Why not just use formatter? In any event, it makes it much more difficult to flatten complex nested data into columns this way.
Can you please make valueAccessor's return value available to the formatter and to the group caption template?
