Custom columns automatically display in ListGrid

i hope that the columns commonName, scientificName , lifeSpan automatically display in ListGrid which are based on “outputs=”commonName,scientificName,lifeSpan”” in dataSource . i can automatically display ListGridFields which are based on value of “outputs” in dataSource(Figure 2).For example,i write (Figure 1)in dataSource .How can i implement above?
