我必须生成一个表并将其导出为html。我最初尝试使用php和phpexcel，但我的客户端服务器要慢（有时我的表有2500个）。现在我尝试通过jquery / ajax获取表并安装js插件进行导出。我目前正在使用数据表和我的代码视图：

工作示例： https://jsbin.com/senufanozo/edit?html,output
它工作正常，2500行对于此代码没有问题，但我无法导出图像。非常需要pdf和excel中的图片。我如何出口呢？
另外如何将pdf页面旋转到横向？
答案 0 :(得分：0)
这可能是一个较晚的答案，但是我要带您解决。
首先，要在使用pdfHtml5的情况下将PDF的方向从纵向更改为横向，您需要按照orientation: 'landscape',定义方向，这将帮助您将PDF文件导出为横向。
使用PDF导出图像需要进行自定义，并且要对图像进行编码，您不能将图像导出为普通的HTML标签，首先应将其编码为base64 encoder
$image = 'http://localhost/img.jpg';
// Read image path, convert to base64 encoding
$type = pathinfo($image, PATHINFO_EXTENSION);
$data = file_get_contents($image);
$imgData = base64_encode($data);
// Format the image SRC: data:{mime};base64,{data};
$src = 'data:image/' . $type . ';base64,'.$imgData;
对图像进行编码后，您需要按以下方式自定义PDF导出
{
extend: 'pdfHtml5',
orientation: 'landscape',
customize: function (doc) {
if (doc) {
for (var i = 1; i < doc.content[1].table.body.length; i++) {
doc.content[1].table.body[i][1] = {
image: '<?php echo $src; ?>,
};
}
}
},
exportOptions: {
stripHtml: false
}
}
这应该可以解决问题。
