    You would need to use orthogonal data for that. Take a look at this example, it's returning a number for the strings to ensure they're in order. You would do something similar, doing a numerical difference in days between now and the date in the table,

    The code structure is good, the use of columns.render is spot on, but your logic and the switch statement looks very wrong:

           var data2 = new Date(milliseconds2);
              switch (data) {
                case today == data2:
                  return 0;
                case today < data2:
                  return 1;
                case today > data2:
                  return 2;
              }
            }
    

    You would be better using if ... else if ... else there instead.

    Another tip would be to convert the dates to UNIX time (seconds since 1970) as that would also be easier to compare. There's docs on the Moment.js site for that,
