JQuery DataTables Merge Same Row Data

Jemru picture Jemru · Nov 4, 2015 · Viewed 17.3k times · Source

I'm using Jquery DataTables.net. I want to merge duplicate value on data table, example I have:

--------------------------------------------
        A         |         1       |     2
--------------------------------------------
        A         |         1       |     4
--------------------------------------------
        A         |         2       |     5
--------------------------------------------

I want them to be like this :

---------------------------------------------
                   |               |     2
                   |         1     |---------
         A         |               |     4
                   |---------------|---------
                   |         2     |     5
---------------------------------------------

How can I do it on DataTables Jquery? Thank you.

We need to handle this in HTML Table .. see the below concept.

$(document).ready(function () {
    $('#example').dataTable();
    MergeGridCells();
});

function MergeGridCells() {
    var dimension_cells = new Array();
    var dimension_col = null;
    var columnCount = $("#example tr:first th").length;
    for (dimension_col = 0; dimension_col < columnCount; dimension_col++) {
        // first_instance holds the first instance of identical td
        var first_instance = null;
        var rowspan = 1;
        // iterate through rows
        $("#example").find('tr').each(function () {

            // find the td of the correct column (determined by the dimension_col set above)
            var dimension_td = $(this).find('td:nth-child(' + dimension_col + ')');

            if (first_instance == null) {
                // must be the first row
                first_instance = dimension_td;
            } else if (dimension_td.text() == first_instance.text()) {
                // the current td is identical to the previous
                // remove the current td
                dimension_td.remove();
                ++rowspan;
                // increment the rowspan attribute of the first instance
                first_instance.attr('rowspan', rowspan);
            } else {
                // this cell is different from the last
                first_instance = dimension_td;
                rowspan = 1;
            }
        });
    }
}
