implement partial update on editable dataframe

[FabienArcellier]

record_mutate modifies a record in the dataframe. This method allows you to create a form that easily update a record in a selected row from a dataframe.

partial modification of the record: By default, the record is completely overwritten. Missing values ​​are replaced with None values. By adding the partial=True flag, only the keys provided as arguments are modified.

state['df'] = EditableDataframe(df)
state['df'].record_mutate(record_index, {'flag': True}, partial=True) # update the column flag of the dataframe to true, trigger a mutation record_update
