Final answer:
To remove Vacation entries from a PivotTable, activate the PivotTable, then uncheck or filter out the 'Vacation' label or data, and the table will update accordingly.
Step-by-step explanation:
To modify the PivotTable and remove Vacation entries, you would first click on the PivotTable to activate it. Then, either uncheck the box next to 'Vacation' in the field list if 'Vacation' is a row or column label, or apply a filter to exclude 'Vacation' if it is part of the data.
After making this change, the PivotTable will update to reflect the removal of the Vacation entries.
