C# 用dataGridView和DataTable显示列表，新增一列时在数据上方出现空行

尝试过将AllowUserToAddRows属性改为Flase，无果
public DataTable table = new DataTable("Product");
private void button1_Click_1(object sender, EventArgs e)
{
DataColumn column1 = new DataColumn();
column1.DataType = System.Type.GetType("System.Object");
column1.ColumnName = "边长";
table.Columns.Add(column1);
foreach (double bian in mDistance)
{
DataRow row;
row = table.NewRow();
row["边长"] = bian;
table.Rows.Add(row);
}

        DataColumn column2 = new DataColumn();
        column2.DataType = System.Type.GetType("System.Object");
        column2.ColumnName = "观测角";
        table.Columns.Add(column2);         
        foreach (double guanjiao in mAngle)
        {
            DataRow row2;
            row2 = table.NewRow();
            row2["观测角"] = guanjiao;
            table.Rows.Add(row2);
        }
        dataGridView1.DataSource = table;
    }

Answer 1

table.Columns.Add(column1);就是加列了
你后面foreach是在加行啊
如果你是希望增加一列后自动填充数据
那你应该循环table赋值，而不是调用rows.add方法
