delete an empty cell in pivot table in Excel

Question

I used the answer @xlm gave me on Reduce number of cells in Excel to make the below pivot table.

How do I get the row with the blank cell to disappear?

Below is the dataset used to create the pivot table:

start,  end,    name,
830,    845,    ppa,
845,    900,    ppa,
900,    915,    Bob Hoskins liam Table,         
915,    930,    Bob Hoskins liam Table,        
930,    945,    Bob Hoskins liam Table,         
945,    1000,   Jack Door,          
1000,   1015,   Jack Door,          
1015,   1030,   Jack Door,          
1030,   1045,   Sara Car Tanya Coffee,

Answer 1

Filter out blanks from Pupils column (Click on the arrow and unselect "blank") and then PivotTable Tools/Options/Sort to sort by date.
