JQuery DataTables合并同一行数据
JQuery DataTables Merge Same Row Data
我使用的是Jquery DataTables.net。我想合并数据表上的重复值，例如：
--------------------------------------------
A | 1 | 2
--------------------------------------------
A | 1 | 4
--------------------------------------------
A | 2 | 5
--------------------------------------------
我希望他们是这样的：
---------------------------------------------
| | 2
| 1 |---------
A | | 4
|---------------|---------
| 2 | 5
---------------------------------------------
如何在DataTablesJquery上执行此操作？非常感谢。
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;
}
});
}

@Kishore Sahasranaman answer不会合并所有重复的单元格值，因为它们被删除而不是隐藏。它正在跳过中的最后一列进行循环条件检查。
$(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;
}
});
}
}
DataTables有一个称为rowsGroup的功能。
下面是一个工作示例。
希望对新来的游客有所帮助。
在@Kishore S.代码上做了一个调整，我想能够对ANY列和我想要的任何表进行分组，但要做到这一点，我需要对以前的列值进行散列，这样，如果你只压缩第3列，它就不会"桥"；上一列。因此：
---------------------------------
Value A | Label1 | 1 |
Value A | Label2 | 1 |
Value A | Label3 | 1 |
Value B | Label1 | 1 |
Value B | Label2 | 1 |
Value B | Label3 | 1 |
---------------------------------
将变为（第1列和第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 | |
---------------------------------
不管怎样，如果有人需要，这里有一些调整：调用方：
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-所以我的代码运行得很好，但jQuery对dataTable的后期处理在呈现时仍然会引起问题，因为在浏览页面时，行会变得不平衡。第一页总是正确的，其他的都会失败。为了解决这个问题，需要添加一个"；重置"；在重新绘制之前取消合并所有内容（请参阅dataTable回调）。因此，下面的示例更新使dataTable在绘制后调用Merge函数（修复了更改显示长度的问题）：
"drawCallback": function( settings ) {
MergeGridCells(TableID,rCols);
},
我认为使用数据表默认行分组选项的最简单方法是：
$('TableID').DataTable({
responsive: true,
'rowsGroup': [0] // You can include all the columns you want to include in the merge
});
然后确保包含这些Javascript文件；
<script type="text/javascript" src="https://cdn.datatables.net/v/dt/dt-1.10.12/datatables.min.js"></script>
<script type="text/javascript" src="https://cdn.rawgit.com/ashl1/datatables-rowsgroup/fbd569b8768155c7a9a62568e66a64115887d7d0/dataTables.rowsGroup.js"></script>
它应该像魅力一样发挥作用☺
