高分跪求——在tableLayoutPanel1下面多加一行

Question

this.tableLayoutPanel1.RowCount++;
            this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, this.tableLayoutPanel1.Height/this.tableLayoutPanel1.RowCount));
            Button btn = new Button();
            btn.Visible = true;
            this.tableLayoutPanel1.Controls.Add(btn, 0, this.tableLayoutPanel1.RowCount - 1);我是想实现在tableLayoutPanel1下面多加一行，而不是在里面，多加一行的格式和tableLayoutPanel1其它行的格式一样？ 

Answer 1

int height = this.tableLayoutPanel1.Height / this.tableLayoutPanel1.RowCount;
this.tableLayoutPanel1.Height += height;
this.tableLayoutPanel1.RowStyles.Add(new System.Windows.Forms.RowStyle(System.Windows.Forms.SizeType.Percent, height));
this.tableLayoutPanel1.RowCount++;

Answer 2

tableLayoutPanel1.Parent.SuspendLayout();
tableLayoutPanel1.Parent.Controls.Add(...);
tableLayoutPanel1.Parent.ResumeLayout();
