Identify the Data Link: Select the table cell that shows the chain link with a padlock icon. This indicates it is linked to an external data source. Locate the Data Link: Right-click the table and choose Data Links. Note the file path of the linked data file. Open the Data Link File: Open the linked data file (e.g., an Excel spreadsheet) in its respective application. Edit the Cell: Make the necessary changes to the cell in the external data file and save the changes. Update in AutoCAD: Return to AutoCAD and the table should automatically update to reflect the changes made in the external file. References: * AutoCAD Help Documentation on Data Linking in Tables
