Adding new event records using the Table window

Steps:

1. Click the Editor menu and click Start Editing.
2. Right-click the event table you want to edit and click Open.
3. Click the arrow on the right to move to the end of the table.
4. Click a cell in the last record and type in a new value. If your events table has been added to ArcMap as a feature layer, the new event appears on the map once valid route location values have been set.

Tip:

Some event tables cannot be edited—for example, delimited text files and tables accessed through an OLE DB connection.
