Question

我在使用Php的FPDF中有一个问题。

我现在在代码中使用的是第1列，它将根据字符长度始终遵循第2列的高度。

问题是只有第2列在起作用。

当我尝试增加第1列中的字符长度时，它将看起来像这样。

当我尝试增加第2列中的字符长度时，它将看起来像这样。

当我尝试增加第3列中的字符长度时，它将看起来像这样。

当一列增加字符长度时，如何使/允许任何最小列高度始终遵循最大单元格高度。

我当前的代码如下。

index.php

        class myPDF extends FPDF

                $this->Ln();

                $this->Cell(275, 1, '',0,0);
                $this->Ln();
                $this->SetFont('Arial','B',6);

                $this->Cell(35,5,'COLUMN 1',1,0);
                $this->Cell(120,5,'COLUMN 2',1,0);
                $this->Cell(120,5,'COLUMN 3',1,0);
                $this->Ln();

        $pdf = new myPDF('L','mm','A4');
        $pdf->AddPage();

        $pdf->HeaderTable();
        $pdf->ViewTable();

        $pdf->Output();

感谢有人可以帮助我解决此问题。

谢谢。

要使用表和多单元格，应将fpdf类扩展为PDF_MC_Table类。 On this page，您会找到可以帮助您的源代码和示例。创建该类是为了与表一起使用，希望对您有所帮助。
