title: Slickgrid id column
body: <p>Is there a way to bypass the necessity for an ID column?  My goal is to display 100,000+ results dynamically.  Currently, the only way I have found to do this is to create an "id" column on the table and then loop through it (which is quite costly).  If this is the case, is there a more efficient way of doing this? How can I hide the column when the grid is displayed?</p>
