Using a class for targets to ordering,displaying in columnDefs

itajackass

My actual option is:

indexes 0 and 6 are dates in the format YYYY-MM-DD.

  "columnDefs": [
        { "orderable": false, "targets": 'azioni' },
        {
            targets: [0],
            data: {
                _: "0.display",
                sort: "0.@data-order",
                type: "0.@data-order"
            }
        },
        {
            targets: [6],
            data: {
                _: "6.display",
                sort: "6.@data-order",
                type: "6.@data-order"
            }
        }
    ]

It works great, but sometime i've to add new columns in the middle, for example in index 2. In this case i've to manually alter also the code to increment by 1 like:

       targets: [7],
            data: {
                _: "7.display",
                sort: "7.@data-order",
                type: "7.@data-order"
            }

Is there a way to create a global option like this?

   "columnDefs": [
        { "orderable": false, "targets": 'azioni' },
        {
            targets: [ column_with_class_date], // i've 2 column with date start and date end
            data: {
                _: "column_with_class_date.display",
                sort: "column_with_class_date.@data-order",
                type: "column_with_class_date.@data-order"
            }
        }
    ]
