Lock Tables

Locking a JMP data table prevents data and column properties from being added or edited. You can still assign row states, run analyses, and so on. To lock a data table, click the red triangle next to the table name in the table panel and select Lock Data Table.

A lock icon appears next to the data table name. To unlock the file, select Lock Data Table again.

If you make a data table read-only outside of JMP (for example, by changing its properties on Windows), the data table contains a note informing you that it is locked (Figure 4.58). This type of lock allows users to edit the data table, but not save the changes.
