问题描述

这听起来像是个菜鸟问题，但由于Python并不是我最好的语言之一，因此我坚持使用它.

This may sound a noob question, but I'm stuck with it as Python is not one of my best languages.

我有一个html页面，里面有一个表格，我想在其中显示一个pandas数据框.最好的方法是什么?使用pandasdataframe.to_html?

I have a html page with a table inside it, and I would like to show a pandas dataframe in it.What is the best way to do it? Use pandasdataframe.to_html?

from flask import Flask;
import pandas as pd;
from pandas import DataFrame, read_csv;

file = r'C:\Users\myuser\Desktop\Test.csv'
df = pd.read_csv(file)
df.to_html(header="true", table_id="table")

html

<div class="table_entrances" style="overflow-x: auto;">

  <table id="table">

    <thead></thead>
    <tr></tr>

  </table>

</div>

推荐答案

工作示例:

python代码:

from flask import Flask, request, render_template, session, redirect
import numpy as np
import pandas as pd


app = Flask(__name__)

df = pd.DataFrame({'A': [0, 1, 2, 3, 4],
                   'B': [5, 6, 7, 8, 9],
                   'C': ['a', 'b', 'c--', 'd', 'e']})


@app.route('/', methods=("POST", "GET"))
def html_table():

    return render_template('simple.html',  tables=[df.to_html(classes='data')], titles=df.columns.values)



if __name__ == '__main__':
    app.run(host='0.0.0.0')

html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

{% for table in tables %}
            {{titles[loop.index]}}
            {{ table|safe }}
{% endfor %}
</body>
</html>

否则使用

return render_template('simple.html',  tables=[df.to_html(classes='data', header="true")])

并从html中删除{{titles[loop.index]}}行

如果您检查html上的元素

if you inspect element on html

<html lang="en"><head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body style="">


            <table border="1" class="dataframe data">
  <thead>
    <tr style="text-align: right;">
      <th></th>
      <th>A</th>
      <th>B</th>
      <th>C</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <th>0</th>
      <td>0</td>
      <td>5</td>
      <td>a</td>
    </tr>
    <tr>
      <th>1</th>
      <td>1</td>
      <td>6</td>
      <td>b</td>
    </tr>
    <tr>
      <th>2</th>
      <td>2</td>
      <td>7</td>
      <td>c--</td>
    </tr>
    <tr>
      <th>3</th>
      <td>3</td>
      <td>8</td>
      <td>d</td>
    </tr>
    <tr>
      <th>4</th>
      <td>4</td>
      <td>9</td>
      <td>e</td>
    </tr>
  </tbody>
</table>


</body></html>

如您所见，它在表html中具有tbody和thead.这样您就可以轻松应用CSS.

as you can see it has tbody and thead with in table html. so you can easily apply css.
