append & data_columns=True
Hello

i create a new store and i am trying to append it.
all is right when i did :
 store.append("table",  dataframe)
but when i did the whole thing with data_columns=dataframe.columns or  data_columns=True
i can write the first append  and then nothing ....
no more data input
tore.append("table",  dataframe,data_columns=dataframe.columns )
any help ?
