我有一个带有可变列数的数据表，我需要向其添加行。
这就是我设置列的方式：
var columns = getColumnsName();
columns.forEach(function(column, index){
dtColumns.push(DTColumnBuilder.newColumn(index).withTitle(column));
});
这仅适用于我未在<tr>内放置<tbody>的情况。如果我在<tr>内放置<tbody>，则会出现以下错误：
TypeError: Cannot read property 'length' of undefined
at _fnGetRowElements (jquery.dataTables.js:3021)
at HTMLTableRowElement.<anonymous> (jquery.dataTables.js:2428)
at jquery.js:144
at Function.map (jquery.js:467)
at jQuery.fn.init.map (jquery.js:143)
at _fnAddTr (jquery.dataTables.js:2427)
at loadedInit (jquery.dataTables.js:1307)
at HTMLTableElement.<anonymous> (jquery.dataTables.js:1332)
at Function.each (jquery.js:374)
at jQuery.fn.init.each (jquery.js:139)
请注意，如果我无法添加<tr>，我就无法在ng-repeat内放置<tbody>来重复我的数据。
我的内部<tr> <tbody>内部<td>内部<td>内容不足<tr>，似乎我收到了上述错误。假设我知道我有多少列并将<table dt-options="ctrl.dtOptions" dt-columns="ctrl.dtColumns" dt-column-defs="ctrl.dtColumnDefs" datatable="ng">
<thead></thead>
<tbody></tbody>
</table>
的确切数字放在using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace HotelWPF
{
public class ReservationVM : INotifyPropertyChanged
{
public Reservation reservation = new Reservation();
private string SecretaryName;
private int RoomNumber;
private string ReservationType;
private DateTime ReservationDate;
public string SecretaryName1
{
get
{
return SecretaryName;
}
set
{
SetProperty(ref SecretaryName, value);
}
}
public int RoomNumber1
{
get
{
return RoomNumber;
}
set
{
SetProperty(ref RoomNumber, value);
}
}
public string ReservationType1
{
get
{
return ReservationType;
}
set
{
SetProperty(ref ReservationType, value);
}
}
public DateTime ReservationDate1
{
get
{
return ReservationDate;
}
set
{
SetProperty(ref ReservationDate, value);
}
}
public void SetProperty<T>(ref T store, T value, [CallerMemberName] string name = null)
{
store = value;
if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedArgs(name));
}
}
}
内，我不会收到此错误...
在这种情况下如何向表中添加行？
修改
正如所提出的，这里是HTML：
PropertyChanged doesn't exist in current context.

注入$ timeout后请尝试以下操作。
$timeout(function(){
var columns = getColumnsName();
columns.forEach(function(column, index){
dtColumns.push(DTColumnBuilder.newColumn(index).withTitle(column));
});
});
