//解决绑定数据后列顺序打乱问题

dataGridView1.Columns["1"].DisplayIndex = 0;

dataGridView1.Columns["2"].DisplayIndex = 1;

dataGridView1.Columns["3"].DisplayIndex = 2;

dataGridView1.Columns["4"].DisplayIndex = 3;

dataGridView1.Columns["5"].DisplayIndex = 4;

dataGridView1.Columns["6"].DisplayIndex = 5;

dataGridView1.Columns["7"].DisplayIndex = 6;

//dataGridView1.Columns["8"].DisplayIndex = 6;

dataGridView1.Columns["9"].DisplayIndex = 7;

dataGridView1.Columns["10"].DisplayIndex = 8;

dataGridView1.Columns["11"].DisplayIndex = 9;

dataGridView1.Columns["12"].DisplayIndex = 10;

1~12均为列名
