定义数组给每一列设置长度

 int[] iaWidth = new int[dtResult.Columns.Count];
                    for (int i = 0; i < dtResult.Columns.Count; i++)
                    {
                        iaWidth[i] = 80;
                    }
                    DevGridControlHelper.BindData(gdcMultiSpec, dtResult, iaWidth);
