如何将dataset中的两个表之一映射到c#中的datagridview

DataSet dataSet = new DataSet();
dataSet.Tables.Add("Table1");
dataSet.Tables.Add("Table2");

// 填充Table1
DataTable table1 = dataSet.Tables["Table1"];
table1.Columns.Add("Column1");
table1.Columns.Add("Column2");
table1.Rows.Add("Value1", "Value2");

// 填充Table2
DataTable table2 = dataSet.Tables["Table2"];
table2.Columns.Add("Column3");
table2.Columns.Add("Column4");
table2.Rows.Add("Value3", "Value4");

DataGridView dataGridView = new DataGridView();
dataGridView.DataSource = dataSet.Tables["Table1"];

private void button_Click(object sender, EventArgs e)
{
    dataGridView.DataSource = dataSet.Tables["Table2"];
}
