DataColumn.Caption属性应用到DataGridView.HeaderText的方法

DataColumn.Caption属性在DataTable绑定到DataGridView上时，并未像想象中那样做为HeaderText来显示。

微软官网貌似说是个小bug，从2.0至今未修正。

DataColumn.Caption属性应用到DataGridView.HeaderText的方法有两种，网上整理：

for (int i = 0; i < table.Columns.Count; i++) {
            if (dataGridView1.Columns.Count >= i) {
                dataGridView1.Columns[i].HeaderText = table.Columns[i].Caption;
            }
        }

或：

private void DataGrid_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
{
    var dGrid = (sender as DataGrid);
    if (dGrid == null) return ;
    var view = dGrid.ItemsSource as DataView;
    if (view == null) return;
    var table = view.Table;
    e.Column.HeaderText = table.Columns[e.Column.Header as String].Caption;
}
