Add column head when copy

[hyh888]

Dear Team,
When copying data from grid to excel, column head couldn't be pasted to excel. Would you like to copy column head for copy action?
Notice: when copy between pqgrid, the column head shouldn't be pasted, it can be judged by pqgrid.

Header cells can be included / excluded from copied data based on the copyModel.header option.

Dear Team,
When I copied data between two pqgrid, the header was pasted to destination cell, it's not what I wanted.
When data were copied to excel, the values of select(column) also pasted to excel, it also a trouble for some extra usfuless data were copied.
