Remove Rows from TableLayoutPanel

Hi there,
I'm desperetely trying to create a method which would delete all rows (which i add through another), but it doesn't seem to work:
Init Paths Method:

        private void InitPaths()
        {
            int c = 1;
            int a = 1;
            while (a < pathRows.Length-1)
            {
                var label = new Label();
                //
                // Label - Format.
                //
                label.Dock = DockStyle.Fill;
                label.AutoSize = false;
                label.Text = pfadZeilen[a];
                label.TextAlign = System.Drawing.ContentAlignment.MiddleLeft;
                label.Size = new System.Drawing.Size(22, 13);
                label.BackColor = System.Drawing.Color.Transparent;
                _LayoutTable.Controls.Add(label, 3, c);
                a++;
                c++;
            }
        }

        private void ClearPaths()
        {   BibTable.RowStyles.RemoveAt(BibTable.RowStyles.Count - 1);
        }

and above (for now only the last row, but i can hopefully get it thorugh a Loop later)is my remove Paths Method (that doesn't work) what i want to accomplish is be able to clear all rows,

after they are inserted.
