Steps
- In Smartsheet's Grid View, locate the cells you want to protect and click the column header above them.
- Click the corresponding Column Menu button that appears for the selected column.
- Select Lock Column from the dropdown list of column options.
- The selected column and all cells beneath it are now locked and protected from edits.
