Disable sorting on last column when using jQuery DataTables
提问by Psyche
I'm using jQuery DataTables in a project and I would like to know how to disable sorting for the last column. I want to implement this site-wide.
我在一个项目中使用 jQuery DataTables，我想知道如何禁用最后一列的排序。我想在整个站点范围内实施这个。
Right now I have the following code:

The aoColumnDefs' aTargets parameter lets you give indexes offset from the right (use a negative number) as well as from the left. So you could do:
aoColumnDefs 的 aTargets 参数允许您提供从右侧（使用负数）以及从左侧偏移的索引。所以你可以这样做：
aoColumnDefs: [
{
bSortable: false,
aTargets: [ -1 ]
}
]
The equivalent new API (for DataTables 1.10+) would be:
等效的新 API（用于 DataTables 1.10+）将是：
columnDefs: [
{ orderable: false, targets: -1 }
]
回答by zessx
I would like to develop the current answer.
我想开发当前的答案。
The good way is to use aoColumnDefsas mentioned.
The default value for the bSortableparameter is true(for each column).
好方法是使用aoColumnDefs如上所述。
该bSortable参数的默认值为true（对于每一列）。
You've got 2 options...
你有2个选择...
By index :
按索引：
var table = $('#example').DataTable({
'aoColumnDefs': [{
'bSortable': false,
'aTargets': [-1] /* 1st one, start by the right */
}]
});
By class :
按班级：
var table = $('#example').DataTable({
'aoColumnDefs': [{
'bSortable': false,
'aTargets': ['nosort']
}]
});
Adding the class on the <th>:
在 上添加类<th>：
<table>
<thead>
<tr>
<th>Foo</th>
<th>Bar</th>
<th class="nosort">Baz</th>
</tr>
</thead>
<tbody>...</tbody>
</table>
回答by ?????
Read here
在这里阅读
$('#example').dataTable({
"aoColumns": [
null,
null,
{ "bSortable": false }, // <-- disable sorting for column 3
null
]
});
http://datatables.net/usage/columnsunder bSortable
You can specify which columns to disable using aoColumnDefsand aTargets
http://datatables.net/usage/columns下 bSortable 您可以指定禁用哪些列使用aoColumnDefs和aTargets
$('#example').dataTable({
"aoColumnDefs": [
{
"bSortable": false,
"aTargets": [ -1 ] // <-- gets last column and turns off sorting
}
]
});
回答by patelarpan
You can use the data attribute data-orderable="false".
您可以使用数据属性data-orderable="false"。
<th data-orderable="false">Salary</th>

$('#example').DataTable()

</table>As of v1.10.5 DataTables can also use initialization options read from HTML5 data-* attributes. This provides a mechanism for setting options directly in your HTML, rather than using Javascript.
从 v1.10.5 开始，DataTables 还可以使用从 HTML5 data-* 属性读取的初始化选项。这提供了一种直接在 HTML 中设置选项的机制，而不是使用 Javascript。

On DataTable 1.9.x:
在数据表 1.9.x 上：
$('.dataTable').dataTable({
'aoColumnDefs': [{
'bSortable': false,
'aTargets': [-1], /* 1st colomn, starting from the right */
}]
});
While on 1.10.x
在 1.10.x 上
$('.dataTable').dataTable({

Its work for me - you can try this
它对我有用 - 你可以试试这个
dataTable({

回答by Brijesh Mavani
This is work perfect for me if you don't allow sorting the first column then use
如果您不允许对第一列进行排序然后使用，这对我来说是完美的
<script>
$(document).ready(function () {
$('#example2').DataTable({
'order':[],
'columnDefs': [{
"targets": 0,
"orderable": false
}]
});
});
</script>
here index row starts with 0, so put 0 in targets.
And if you disable sorting for one or more column then use,
这里索引行从 0 开始，所以把 0 放在目标中。
如果您对一列或多列禁用排序，则使用，
<script>
$(document).ready(function () {
$('#example2').DataTable({
'order':[],
'columnDefs': [{
"targets": [0,3],
"orderable": false
}]
});
});
</script>
Here you can see ,
在这里你可以看到，
Above my checkbox column at 0 positions and Action column at 3rd position so sorting disable in both table.
在 0 位置的复选框列和第 3 位置的操作列上方，因此在两个表中都禁用排序。
回答by MR_AMDEV
This would be useful for v1.10+ of datatables. Set column number for which you want to remove sorting for e.g 1st column would be like:
这对 v1.10+ 的数据表很有用。设置要为其删除排序的列号，例如第一列：
columnDefs: [
{ orderable: false, targets: 0 }
]
For multiple columns(1st,second and third):
对于多列（第一、第二和第三）：
columnDefs: [
{ orderable: false, targets: [0,1,2] }
]
回答by Dip
for disable sorting on any column in datatable use the following
要禁用对数据表中的任何列进行排序，请使用以下内容
aoColumnDefs: [{ "aTargets": [ 0 ], "bSortable": false}],
it means "aTargets": [ 0 ]is the column id starting from 0
这意味着 "aTargets": [ 0 ]是从 0 开始的列 id
so in your case it becomes:
所以在你的情况下它变成：
$(".tableSort").dataTable({
aaSorting: [[0, 'asc']],
aoColumnDefs: [
{ "aTargets": [ -1 ], "bSortable": false},
]
});
