2、画一条线：
2.1方法解说
/*画一条线：
x1：线条起点x坐标
y1：线条起点y坐标
x2：线条终点x坐标
y2：线条终点y坐标
style：SetLineStyle的效果一样
*/
// $pdf->Line($x1, $y1, $x2, $y2, $style=array());
2.2方法使用：
/*线的颜色*/
$this->SetLineStyle(array('width' => 0, 'cap' => 'butt', 'join' => 'miter', 'dash' => '0', 'color' => array(220, 20,60)));
/*画一条线*/
$this->Line(1, 100, 100, 1, $style=array()); /*加入一条下划线 下划线颜色默认为黑色，用此方法【SetLineStyle()】可以自定义线的颜色 */
$this->Cell(180, 0, '', 1, 0, 'C', 0, '', 0, true);
