Is there any way to print the python dictionary in to a table in HTML. I have a python dictionary and am sending to HTML by using 

return render_template('index.html',result=result)

Now I need to print the elements in result dictionary in to HTML as a table.

Flask 使用 Jinja 作为模板框架。您可以在模板 (html) 中执行以下操作

Jinja 也可以单独用作标记渲染器。

Python3 / Jinja2

<table>
  <thead>
    <tr>
      <th>Key</th>
      <th>Value</th>
    </tr>
  </thead>
  <tbody>
  {% for key, value in result.items() %}
   <tr>
       <td> {{ key }} </td>
       <td> {{ value }} </td>
   </tr>
  {% endfor %}
  </tbody>
</table>

Python2/神社

<table>
{% for key, value in result.iteritems() %}
   <tr>
        <th> {{ key }} </th>
        <td> {{ value }} </td>
   </tr>
{% endfor %}
</table>

检查烧瓶表。

文档中的示例（稍作编辑）：

from flask_table import Table, Col

# Declare your table
class ItemTable(Table):
    name = Col('Name')
    description = Col('Description')

items = [dict(name='Name1', description='Description1'),
         dict(name='Name2', description='Description2'),
         dict(name='Name3', description='Description3')]

# Populate the table
table = ItemTable(items)

# Print the html
print(table.__html__())
# or just {{ table }} from within a Jinja template

我有更好的运气将字典放入列表中，然后让 html 循环遍历列表并打印表格。蟒蛇将是：

Table = []
for key, value in results_dict.iteritems():    # or .items() in Python 3
    temp = []
    temp.extend([key,value])  #Note that this will change depending on the structure of your dictionary
    Table.append(temp)

然后在你的 html 中循环遍历表格。

<table>
{% for t in table %}
    <tr>
    {% for i in t %}
        <td>{{ i }}</td>
    {% endfor %}
    </tr>
{% endfor %}
 </table>

所以我想要一种简单的方法来从只有内联样式的python字典生成html（因为电子邮件）并且找不到任何我满意的东西所以我写了这个，

它使用起来非常简单，并且很容易添加样式到

<table style="margin: 3px">
    <tr style="background-color: #7cc3a97d">
        <th style="color: white">col1</th>
        <th style="color: white">col2</th>
        <th style="color: white">col3</th>
        <th style="color: white">col4</th>
    </tr>

    <tr style="background-color: aliceblue">
        <td style="padding: 1rem">value11</td>
        <td style="padding: 1rem">value21</td>
        <td style="padding: 1rem">value31</td>
        <td style="padding: 1rem">value41</td>
    </tr>
    <tr style="background-color: #c2d4e4">
        <td style="padding: 1rem">value12</td>
        <td style="padding: 1rem">value22</td>
        <td style="padding: 1rem">value32</td>
        <td style="padding: 1rem">value42</td>
    </tr>
    <tr style="background-color: aliceblue">
        <td style="padding: 1rem">value13</td>
        <td style="padding: 1rem">value23</td>
        <td style="padding: 1rem">value33</td>
        <td style="padding: 1rem">value43</td>
    </tr>
</table>

假设您有以下字典

myDict = {
    'col1' : ['value11', 'value12', 'value13'],
    'col2' : ['value21', 'value22', 'value23'],
    'col3' : ['value31', 'value32', 'value33'],
    'col4' : ['value41', 'value42', 'value43'],
}

它可以转换为

class HTML:

    def __init__(self, Header, tableStyles = {}, trStyles = {}, thStyles = {}):
        self.tableStyles = HTML._styleConverter(tableStyles)
        trStyles = HTML._styleConverter(trStyles)
        thStyles = HTML._styleConverter(thStyles)
        self.rows = []
        self.Header= f'<tr {trStyles} >'
        for th in Header:
            self.Header += f'\n<th {thStyles} >{th}</th>'
        self.Header += '\n</tr>'

    @staticmethod
    def _styleConverter(styleDict : dict):
        if styleDict == {}:
            return ''
        styles = ''
        for [style, value] in styleDict.items():
            styles +=f'{style}: {value};'
        return f'style="{styles}"'

    def addRow(self, row, trStyles = {}, tdStyles = {}):
        trStyles = HTML._styleConverter(trStyles)
        tdStyles = HTML._styleConverter(tdStyles)
        temp_row = f'\n<tr {trStyles} >'
        for td in row:
            temp_row += f'\n<td {tdStyles} >{td}</td>'
        temp_row += '\n</tr>'
        self.rows.append(temp_row)


    def __str__(self):


        return \
f'''
<table {self.tableStyles} >
{self.Header}
{''.join(self.rows)}
</table>
'''



def dictionaryToHTMLTable(dict : dict):
    html = HTML(Header = dict.keys(),
                tableStyles={'margin': '3px'},
                trStyles={'background-color': '#7cc3a97d'},
                thStyles={ 'color': 'white'})
    for i, row in enumerate(zip(*dict.values())):
        print(row)
        if i%2 == 0:
            BGC = 'aliceblue'
        else:
            BGC = '#c2d4e4'
        html.addRow(row, trStyles={'background-color' : BGC}, tdStyles={'padding': '1rem'})
    return html

并输出

print(dictionaryToHTMLTable(myDict))

对于python3，result.items后面没有()

<table>
{% for key, value in result.items %}
   <tr>
        <th> {{ key }} </th>
        <td> {{ value }} </td>
   </tr>
{% endfor %}
</table>

使用遍历字典项result.iteritems()，然后将键/数据写入 html 表的行。

#!/usr/bin/env python3

tbl_fmt = '''
<table> {}

row_fmt = '''
  <tr>
    <td>{}</td>
    <td>{}</td>

def dict_to_html_table(in_dict):
    return tbl_fmt.format(''.join(row_fmt.format(k, v) for k, v in in_dict.items()))


if __name__ == "__main__":

    print(d)
