Issue
This may sound a noob question, but I'm stuck with it as Python is not one of my best languages.
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?
py
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>
Solution
working example:
python code:
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>
or else use
return render_template('simple.html', tables=[df.to_html(classes='data', header="true")])
and remove {{titles[loop.index]}} line from html
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>as you can see it has tbody and thead with in table html. so you can easily apply css.
