The HashCode of DataSource has not changed whenselecting and deleting all

Describe the bug

我在使用table时，当我全选数据后，执行删除操作，我将通过对话框的方式确认数据是否删除，当点击对话框的确认按钮后，数据是真实的删除了，但是神奇的是table居然没有变化（我在执行完删除操作后进行了查询处理）

@XueDee123 hi, I debugged the program and found that it is very interesting that this issue only occurs when selecting and deleting all, then I found that the Table has rewritten ‘ShouldRender’, and you set RenderMode='RenderMode. ParametersHashCodeChanged', but the HashCode of DataSource has not changed, so the Table’s re-rendering is blocked.

The solution to this problem is set RenderMode='RenderMode.Always'. Perhaps there are other better solutions, but I haven’t found them.

@ElderJames In principle, resetting _ VmTableModel=new (data, null) each time will also cause the hash to change, but it’s not, please pay attention to this issue.

@XueDee123 For now, please call _table.ReloadData for workaround.

    protected async Task DeleteHandleOk(MouseEventArgs e)
    {
        _delModal.Loading = true;
        var keys = _vmTableModel.Selected.Select(b => b.Name).ToList();
        data.Where(b => keys.Contains(b.Name)).ToList().ForEach(b => data.Remove(b));
        _vmTableModel.Source = null;
        _vmTableModel.Source = data;
        _delModal.Visible = false;
        _delModal.Loading = false;
+       _table.ReloadData();
    }
