  The answer is it depends

  The columns option is generally used when defining options for each column, like columns.data. In this case the advantage of columnDefs is to apply the same config options to multiple columns. The code in the thread you linked could be reduced to this:

          columnDefs: [
              {
                  targets: [0],
                  visible: true,
                  searchable: true,
                  orderable: true
              },
              {
                  targets: [1,2,3,4,5,6,7,8],
                  visible: false,
                  searchable: false,
                  orderable: false
              },
              {
                  targets: [9],
                  visible: true,
                  searchable: false,
                  orderable: false
              },
         ],
         columns: [ .... ],
  

  The first one, using columnDefs.targets [0], is not needed as those are all default values.

  columnDefs is also useful when you aren't using columns to define all the columns. Otherwise you will need to do something like the columns example.

  You will want to understand the columnDefs conflict resolution rules.

  ah, i see. so even if you are using columns.data to define the columns, it could be a timesaver to not define other properties there if they are shared by other columns. you would use columnDefs to group columns with the same properties. so that is a case where you would use both methods, like in your example.

  very interesting. time to go through all my projects and do some code cleanup.
