This article describes how to go from a standard table...
...to a table where columns with a sample size under a specified threshold (e.g. 50) are made blank:
A table with rows and columns.
1. Select your table.
2. Go to Properties > RULES on the object inspector.
3. To apply the rule, select the Plus (+) > Browse Online Library > Modify Cell Content > Blank Cells with Small Sample Sizes.
4. Select the appropriate threshold under Minimum Column n.
5. Press OK.
Note, this rule uses the Column Sample Size for blanking the cells. A footer note is also added which specifies this condition.
