Comparison Settings in Parser

When the final parser output is in table form (in single-variable pattern, the output is not in table form), you can selected some columns from the output table, which will be compared in Golden baseline to detect changes. 

To configure the Comparison Setting, complete the following steps：

1. Select a column in the output table to be set as interface key or table key. Click the  icon of the target column, then click Set as Table Key. in this example, the $route_map_name column is set as the table key. The values in this column will be used as reference for comparison. 
   
   
2. Click the  icon, then select Comparison Settings from the dropdown menu. Check the checkbox to select columns to be compared. The column that is set as interface key or table key in step 1 will be selected by default. 
   
   
3. Click OK in the Comparison Settings window to close this window and save the settings.
