Question

我正在使用Jquery DataTables.net。我想在数据表上合并重复值，例如我有：

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

我希望他们是这样的：

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

我如何在DataTables Jquery上做到这一点？谢谢。

我们需要在HTML表中处理这个问题..请参阅以下概念。

$(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

对@Kishore S. 代码进行了调整，我希望能够对任何列和我想要的任何表进行分组，但为此我需要前一列值的散列，以便如果您只压缩第 3 列，它不会“桥接”上一列。所以：

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

会变成（承认第 1 和第 3 列）：

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

代替：

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

无论如何，如果有人需要，这里有一些调整：调用方式：

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+"> tbody > tr").children("td").attr('hidden', false);
    $("#"+TableID+"> tbody > tr").children("td").attr('rowspan', 1);
    $("#"+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;
      }
    });
  }
}

UPDATE - 所以我的代码运行良好，但是数据表的 jQuery 后处理在呈现时仍然会导致问题，因为当您浏览页面时行会变得不平衡。第一页永远是对的，其他的就会失败。要解决此问题，需要添加“重置”以在重绘之前取消合并所有内容（请参阅dataTable callback）。因此，下面的示例更新使 dataTable 在绘制后调用您的 Merge 函数（也修复了更改显示长度的问题）：

 "drawCallback": function( settings ) {
        MergeGridCells(TableID,rCols);
    },

Answer 3

@Kishore Sahasranaman答案不会合并所有重复的单元格值，因为它们已被删除而不是被隐藏。在跳过循环条件检查的最后一列。

$(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;
            }
        });
    }
}

rowsGroup有一个称为DataTables的功能。
