如何解决如何对仅在数据表中具有数字的列进行排序？
排序仅在具有整数值的列中不起作用。它按数字比较数字。一个解决方案将不胜感激。定义列数字不起作用。是否需要更改其他内容？为了清楚起见，我在表中添加了一些值。
Attachedimage is of descending order
HTML：
$(document).ready(function() {
$('#tblLocks').dataTable();
});

</table>JS：
var table = $('#tblLocks').DataTable({
responsive: true,autoWidth: false,serverSide: true,processing: true,},ajax:{
url: "@Url.Action("LoadLocks","Locks")",type: "POST",dataType: "json",dataSrc: function (json) {
return json.data["LockCommonViewModels"];
}
},columns: [
{ data: "SerialNumber",name: "SerialNumber",autoWidth: true },{ data: "CustomerName",name: "CustomerName",{ data: "CustomerCode",name: "CustomerCode",{ data: "ManufactureDate",name: "ManufactureDate",],order: [[3,"desc"]]
});
解决方法
如注释中所建议的那样，排序就像列type是字符串一样。但是有一个设置（https://datatables.net/reference/option/columns.type）可以覆盖默认解释，您可以在其中告诉它每一列中的数据类型（默认解释为空）。
您可以在下面的示例中在第3列和第4列上看到不同的排序变化，具体取决于它是以字符串还是数字形式读取数据。如果在CustomerCode (num)列上进行排序，则按照您的建议工作，但如果在CustomerCode (string)列上进行排序，则如示例所示进行排序。
我建议为CustomerCode列显式设置此值，并且排序应按预期进行。
$(document).ready(function() {
$('#tblLocks').dataTable({
order: [
[2,"desc"]
],"columns": [
null,null,{
"type": "string"
},{
"type": "num"
},null
]
});
