1、composer require tecnickcom/tcpdf
2、在控制器中use TCPDF;
3、

// Set some content to print

}如果生成的页面需要是一个表格,那么注意以下事项:
1、手动换行
<tr nobr="true"> <td>your content here</td> </tr>
2、可以设置css:
$html = <<<EOD
<style>
div{
maring-left:20px;
}
td{
border:1px solid #ccc;
font-size:16px;
line-height:130%;
}
p{font-size:16px}
</style>
<h2 style="margin-top:15px">$productData[product_name]</h2>
<p>Catalog Number:$productData[catalog_number]</p>
<table cellspacing="0" cellpadding="10">
<tr style="color:#fff;background-color:#1c6aba;font-weight:bold;line-height:36px"><td colspan="2"> DESCRIPTION</td></tr>
<tr><td width="30%">Product Name</td><td width="70%">$productData[product_name]</td></tr>
<tr><td width="30%">Gene Name</td><td width="70%">$productData[gene_name]</td></tr>
<tr><td width="30%">Source</td><td width="70%">$productData[source]</td></tr>
<tr><td width="30%">Alternative names</td><td width="70%">$productData[alternative_names]</td></tr>
</table>
<table cellspacing="0" cellpadding="10">
<tr style="color:#fff;background-color:#1c6aba;font-weight:bold;line-height:36px"><td colspan="2"> SPECIFICATIONS</td></tr>
$spe_thml
</table>
<table cellspacing="0" cellpadding="10">
<tr style="color:#fff;background-color:#1c6aba;font-weight:bold;line-height:36px"><td colspan="2"> BACKGROUND</td></tr>
<tr><td width="30%" >Gene Accession</td><td width="70%" >$productData[gene_accession]</td></tr>
<tr><td width="30%" >Gene Alias</td><td width="70%" >$productData[gene_alias]</td></tr>
<tr><td width="30%">Background</td><td width="70%">$productData[background]</td></tr>
</table>
EOD;3、是否自动翻页:
// 设置是否自动分页 距离底部多少距离时分页 $pdf->SetAutoPageBreak(false, '15');
