php - 我们在哪里可以指定 pdf 中生成的列的宽度？

Question

我已经使用fpdf库生成了一个 pdf。数据被导出到 pdf 文档我想设置单个列单元格的宽度如何做我知道在这个函数中必须做一些事情来增加宽度 function CalcWidths($width,$align) { //Compute the widths of the columns $TableWidth=0; foreach($this->aCols as $i=>$col) { $w=$col['w']; if($w==-1) $w=$width/count($this->aCols); elseif(substr($w,-1)=='%') $w=$w/100*$width; $this->aCols[$i]['w']=$w; $TableWidth+=$w; } if($align=='C') $this->TableX=max(($this->w-$TableWidth)/2,0); elseif($align=='R') $this->TableX=max($this->w-$this->rMargin-$TableWidth,0); else $this->TableX=$this->lMargin; } 什么必须改变

宽度可以像这样分配fpdf，

 $options = array('cols' =>
                        array('Detail1' => array('width'=>100, 'justification' => 'left'),
                              'Detail2' => array('width'=>400, 'justification' => 'left')
                             )
                       );

但是字段值会扩展，然后宽度也会增加。然后像这样使用

$table[] = array(
                array("Detail1" => "D1", "Detail2" => wordwrap($x1, 200, "\n", 1)),
                array("Detail1" => "D2", "Detail2" => wordwrap($x2, 200, "\n", 1)),
                array("Detail1" => "D3", "Detail2" => wordwrap($x3, 200, "\n", 1))
);
