当我以PDF格式查看我的html页面时遇到问题。问题是当数值很大时，它会打破减号和值之间的界限。
以下是hmtl页面的示例，它完美无缺 enter image description here
然后，当我将其转换为PDF时，它看起来像这样： enter image description here
在这里，我将我的页面渲染为完整的HTML文档：
def document_to_html_document(document):
"""
Renders the invoice to a full html document with <html>, <head>, and <body> tags.
"""
return render_to_string('invoice_print.html', {
'body': document_to_html(document),
'document': document,
'base_url': settings.SITE_BASE_URL
})
我构建HTML字符串并将其转换为pdf的代码：
def document_to_pdf(document, server_base_url, target=None):
# Build HTML string
html = document_to_html_document(document)
# Setup input and output files
html_file = tempfile.NamedTemporaryFile(suffix='.html')
html_file.write(document_to_html_document(document).encode())
target = target or tempfile.NamedTemporaryFile()
# Convert to pdf
command = 'xvfb-run wkhtmltopdf --footer-right "[page]/[topage]"{s} {o}'.format(
s=html_file.name,
o=target.name
)
s = subprocess.Popen(command, shell=True)
s.communicate()
# Return pdf bytes
target.seek(0)
return target.read()
这是我的hmtl代码，我添加了“body”：
<html>
<head>
<title>MOSEK-{{ document }}</title>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<!-- JQuery -->
<script src="{{ base_url }}static/assets/vendor/jquery-1.11.1.js"></script>
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="{{ base_url }}static/assets/vendor/bootstrap-3.1.1-dist/css/bootstrap.min.css">
<!-- Optional theme -->
<link rel="stylesheet" href="{{ base_url }}static/assets/vendor/bootstrap-3.1.1-dist/css/bootstrap-theme.css">
<!-- Latest compiled and minified JavaScript -->
<script src="{{ base_url }}static/assets/vendor/bootstrap-3.1.1-dist/js/bootstrap.min.js"></script>
<style>
body {
width: 950px;
}
</style>
</head>
<body>
<div>
<div class="container">
{{ body|safe }}
</div>
</div>
</body>
我不知道如何解决它，任何帮助将不胜感激：）
这是Invoice_body的内容：

<div class="col-xs-12">
