Question

我正在使用PHP / TCPDF中的Multicell（）函数创建一个pdf表。我面临的两个问题是

表格的每一行（3x3）都有不同数量的数据线，所以考虑到各行的最大行数，如何为每一行绘制水平线。

如何解决分页符问题？例如，如果第2行数据流入下一页。如何在新页面中重新编写完整的表格，或者在包含表格子标题的新页面中开始第2行？对这两种情况的任何输入都表示赞赏。我通过本文http://www.onemoretake.com/2009/03/27/revisited-tcpdf-variable-height-table-rows-with-multicell/

的输入尝试了以下内容

public function xyz($arr_1){
$f1 = $arr_1[f1];
$f2 = $arr_1[f2];
$f3 = $arr_1[f3];
$numL1 = substr_count($f1, "\n" );
$numL2 = substr_count($f2, "\n" );
$numL3 = substr_count($f3, "\n" );
$Maxrowlines = max($numL1, $numL2, $numL3)*6;
if($this->GetY() + $Maxrowlines  > $this->PageBreakTrigger){
            $this->AddPage();
        }
$startx = $this->GetX();
$starty = $this->GetY();
$rowmaxy = $starty + $Maxrowlines;
$this->MultiCell(40,10,$txt = $arr_1[f1],'0','L',0, $ln =0);
$this->MultiCell(40,10,$txt = $arr_2[f2],'0','L',0, $ln =0);
$this->MultiCell(40,10,$txt = $arr_3[f3],'0','L',0, $ln =0);
$this ->SetXY($startx, $starty);
$tempy = $this->GetY();
    $this->SetXY($startx, $tempy);
    if($temp < $rowmaxy){
        $diffy = $rowmaxy - $tempy;
        $this->MultiCell(40,$diffy, '' , '0', 'C', 0);
    } else {
        $this->MultiCell(40,0,'','0','C',0);
    }
        $addx = $this->GetX();
        $startx+= $addx;    
}
$arr_1 = array(f1=> $apple , f2=> $oranges, f3=> $mangoes);                 
$pdf->xyz($arr_1);

修复很容易。花了一些时间，这是修复。

# define methods and classes-----------------
# constructors....class...
public function xyz($arr_1){
     $f1 = $arr_1[f1];
     $f2 = $arr_1[f2];
     $f3 = $arr_1[f3];
    $numL1 = substr_count($f1, "\n" );
    $numL2 = substr_count($f2, "\n" );
    $numL3 = substr_count($f3, "\n" );
    $Maxrowlines = max($numL1, $numL2, $numL3)*6;

      $startx = $this->GetX();
      $starty = $this->GetY();
      $rowmaxy = $starty + $Maxrowlines;
$this ->SetXY($startx, $starty);
      $this->MultiCell(40,10,$txt = $arr_1[f1],'0','L',0, $ln =0);
      $this->MultiCell(40,10,$txt = $arr_2[f2],'0','L',0, $ln =0);
      $this->MultiCell(40,10,$txt = $arr_3[f3],'0','L',0, $ln =0);
    # Now, if the lines in a multicell are overflowing into next row
    # get current Y position store it in a variable
    # SetXY to the current Y and if the tempy is less than the rowmaxy we..
    # calculate extend cell height with that difference 

        $tempy = $this->GetY();
            $this->SetXY($startx, $tempy);
            if($tempy < $rowmaxy){
            $diffy = $rowmaxy - $tempy;
            $this->MultiCell(40,$diffy, '' , '0', 'C', 0);
            } 
  }
#--------------Call the functions.........
#..... invoke the main class and methods...
# main code as follows..
$arr_1 = array(f1=> $apple , f2=> $oranges, f3=> $mangoes);
$rowcount = max($pdf->getNumLines($arr_1 ['f1'],40),
                                $pdf->getNumLines($arr_1['f2'],40),
                                $pdf->getNumLines($arr_1 ['f3'],40));
$height_of_cell = $pdf->GetY()+($rowcount*6); # 6 is adjustment of the
# height to font you use. My case, `helvetica`
$dimensions = $pdf->getPageDimensions();
$page_height = $dimensions['hk'];# standard value 286;
$bottom_margin = $dimensions['bm'];# standard value of 20
if($height_of_cell > $page_height - $bottom_margin) {   
    $pdf->AddPage();
    $pdf->your_TableHeader();# call table header if there is one
    $pdf->Ln(10); # No. Line you want to start printing data below header 
}
$pdf->xyz($arr_1);

更新，看起来这个答案并不能解决特定于1行的所有行的溢出问题。任何建议或改进都被接受。另一方面，分页符合完美。
