However, the template arguments are not types; rather, aliases.

new_data is a local variable. So, this instantiation of ColumnTable is 
with that symbol.

Likewise, that instantiation of ColumnTable is with the symbols 'names', 
'salary', and 'age'. Is that what you want? Or do you want to 
instantiate with their types? Can you explain some more what you are
