PYSimpleGUI Table that shows formatted data

Question

Im trying to obtain with PYSimpleGUI table with formatted numbers (no decimals numbers). I take data from Dataframe and able to create table but without formatting. If I try to format numbers on dataframe directly with style.format then during Table creation I recieve "Styler error". So I understand that I have first push DF into Table creation and then somehow format values. How to change format to {:,.0f} in table view. I looked for examples and cookbook but found no information about that.

import pysimplegui as sg
import pandas as pd

df = pd.DataFrame([[100.045, 212504.4588], [34658.13489, 445598.465498], [546589.466, 646549.4847], [71214.4986, 8498779.46598]], columns=["A", "B"])
layout = [[sg.Table(values=df,
                    display_row_numbers=True,
                    auto_size_columns=False,
                    num_rows=min(25, len(data)))]

window = sg.Window('Table', layout, grab_anywhere=False)
event, values = window.read()
window.close()

So far I receive table that looks like:

   A           B
0  100.045     212504.4588
1  34658.13489 445598.465498
....

I would like to achieve table that looks like:

   A         B
0     100    212,504
1  34,658    445,598
....

Along with a few other fixes to your code, you need to use the package numpy as well to change the dtype from float64 to int64 shown in the code below

import PySimpleGUI as sg
import pandas as pd
import numpy as np

def df_gui():
    df = pd.DataFrame(columns=["A", "B"],
                      data=np.array([[100.045, 212504.4588], [34658.13489, 445598.465498], [546589.466, 646549.4847],
                                     [71214.4986, 8498779.46598]]))
    df['A'] = df['A'].astype(np.int64)
    df['B'] = df['B'].astype((np.int64))
    values = df.values.tolist()
    headers = df.columns.values.tolist()


    layout = [[sg.Table(headings=headers, values=values, display_row_numbers=True, auto_size_columns=False, num_rows=min(25, len(values)))]]

    window = sg.Window('Table', layout, grab_anywhere=False)
    while True:
        event, value = window.read()

        if event == sg.WIN_CLOSED:
            break
    window.close()
df_gui()

TIP: run event, values = window.read() in a while True: loop. this will keep the window open, reading the event and values when ever something is clicked, until the x is pressed in the window which breaks the loop

You need to convert the data to requested format by yourself.

import PySimpleGUI as sg
import pandas as pd

data = [
    [100.045, 212504.4588],
    [34658.13489, 445598.465498],
    [546589.466, 646549.4847],
    [71214.4986, 8498779.46598],
]

df = pd.DataFrame(data, columns=["A", "B"])
table_data    = list(map(lambda x:list(map(lambda d:f'{d:,.0f}', x)), df.values.tolist()))
table_headers = df.columns.values.tolist()

layout = [[sg.Table(table_data, headings=table_headers, display_row_numbers=True,
    auto_size_columns=False, num_rows=min(25, len(data)))]]

sg.Window('Table', layout, grab_anywhere=False).read(close=True)
