JQuery DataTables 合并相同行数据

Question

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.

Answer 1

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; } }); } }

Answer 2

@Kishore Sahasranaman answer does not merge all the repeated cell values because they were deleted instead of being hidden. It was skipping last column in for loop condition check.

$(document).ready(function () {
    $('#example').dataTable({
            "scrollX": true,
            "scrollY": "600px",
            "responsive" : false,
            "ordering" : false,
            "paging" : false,
            "searching" : false
    });
    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();
                dimension_td.attr('hidden', true);
                ++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;
            }
        });
    }
}

Answer 3

There is a feature called rowsGroup to the DataTables .

Here is a working example.

Hope that would help the new visitors here.

Answer 4

Did a tweak on @Kishore S. code, I wanted to be able to group ANY column and on whatever table I wanted, but to do so I needed a hash of the previous column values so that if you ONLY condense column 3, it doesn't "bridge" over a previous column. So:

---------------------------------
Value A    |  Label1     |   1  |
Value A    |  Label2     |   1  |
Value A    |  Label3     |   1  |
Value B    |  Label1     |   1  |
Value B    |  Label2     |   1  |
Value B    |  Label3     |   1  |
---------------------------------

Would become (condesing columns 1 and 3):

---------------------------------
           |  Label1     |      |
Value A    |  Label1     |   1  |
           |  Label1     |      |
           |  Label2     |   1  |
Value B    |  Label3     |   1  |
           |  Label4     |   1  |
---------------------------------

Instead of:

---------------------------------
           |  Label1     |      |
Value A    |  Label1     |      |
           |  Label1     |   1  |
           |  Label2     |      |
Value B    |  Label3     |      |
           |  Label4     |      |
---------------------------------

Anyway, here's the tweaks if anyone needs them: Called with:

MergGridCells('MyTableID',[1,3]);

function MergeGridCells(TableID,rCols) {
  var dimension_cells = new Array();
  var dimension_col = null;
  for(Col in rCols) {
    dimension_col=rCols[Col];
    // first_instance holds the first instance of identical td
    var first_Hash="";
    var first_instance = null;
    var rowspan = 1;
    // iterate through rows
    $("#"+TableID).find('tr').each(function () {
      // find the td of the correct column (determined by the dimension_col set above)
      var dimension_td = $(this).find('td:nth-child(' + dimension_col + ')');
      var dim_Hash="";
      for(x=1;x<dimension_col;x++){
        dim_Hash+=$(this).find('td:nth-child(' + x + ')').text();
      }
      if (first_instance === null) {
          // must be the first row
          first_instance = dimension_td;
      } else if (dimension_td.text() === first_instance.text() && first_Hash === dim_Hash) {
          // the current td is identical to the previous AND the Hashes are as well
          // remove the current td
          // dimension_td.remove();
          dimension_td.attr('hidden', true);
          ++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;
          first_Hash = dim_Hash;
          rowspan = 1;
      }
    });
  }
}
