Additional Columns

Hi

This plugin is great for me to display my wild cetacean information but I was wondering, is there any way I can add more than 9 additional columns? I need to add 14 in total to display all the information I need.

Or could I rename the default columns?

Thanks in advance.

columns i need:
Name
ID
Gender
Birth Year
Birth Month
Mother
Father
Clan
Matriarch
Species
Death Year
Estimated Age at Death
Cause of Death
Biography
Location
