Use the renumbering command to renumber table tags before creating tables.
In this release of AutoCAD Civil 3D, the table tag renumbering command is available from the Tables contextual tab. It is also available from the Labels & Tables panel on contextual tabs for objects that support tags, such as Alignment and Parcel.
For more information, see Renumbering Label Tags. The Table Tag setting process is now a drawing-wide setting. See Creating Label Tags for more information.
