Hi,
Regarding a feature request for allowing setting Signed/Unsigned attribute by using central columns. I have implemented it by adding an extra column named 'col_Attribute' in central columns table so as there would be no confusion regarding it but as quoted by Madhura on github there will be many problem regarding this. So I need suggestion if it is required to add a new column or it would be enough by just adding 'attributes' to the 'col_extra' column.
Thanks and Regards.
