Performance table and ISA variations ?

Asked by: 4290 views Private Pilot

I'm self studying for my PPL ground school,and i'm puzzled about cruise power settings  table.

If you are calculating cruise performance on a certain pressure altitude and temperature is (+10 ISA )for example ,can you still use this table --by interpolation for example-? 

or are there another tables which has columns for different ISA variations ,since the table only has columns for (+20 ISA) and (-20 ISA) ? 
for ex (+5 ISA , -15 ISA ...etc )
Thanks in advance
