PySimpleGUI - Table Element
The Table object is a useful GUI widget in any GUI library. Its purpose is to display a two-dimensional data structure of numbers and strings in a tabular form having rows and columns.
The important parameters to be passed to the Table class constructor are −
PySimpleGUI.Table(values, headings, col_widths, auto_size_columns, select_mode, display_row_numbers, num_rows, alternating_row_color, selected_row_colors, header_text_color)
The following table explains the role of each of these parameters −
Sr.No. | Parameter & Description |
---|---|
1 | Values Table data represented as a 2-dimensions table |
2 | Headings The headings to show on the top line |
3 | col_widths Number of characters that each column will occupy |
4 | auto_size_columns If True columns will be sized automatically |
5 | select_mode Select Mode. Valid values:
|
6 | display_row_numbers If True, the first column of the table will be the row |
7 | num_rows The number of rows of the table to display at a time |
8 | alternating_row_color If True every other row will have this color in the background. |
9 | selected_row_colors Sets the text color and background color for a selected row. |
10 | header_text_color sets the text color for the header |
When any cell in the table is clicked, PySimpleGUI generates a tuple of CLICKED event having the table key, and the (row,col) of the clicked cell.
event: ('-TABLE-', '+CLICKED+', (0, 1))
Following code displays a list of students in a Table object on the PySimpleGUI window. A popup window appears when you click in any cell. The cell coordinates are displayed on the popup.
import PySimpleGUI as psg psg.set_options(font=("Arial Bold", 14)) toprow = ['S.No.', 'Name', 'Age', 'Marks'] rows = [[1, 'Rajeev', 23, 78], [2, 'Rajani', 21, 66], [3, 'Rahul', 22, 60], [4, 'Robin', 20, 75]] tbl1 = psg.Table(values=rows, headings=toprow, auto_size_columns=True, display_row_numbers=False, justification='center', key='-TABLE-', selected_row_colors='red on yellow', enable_events=True, expand_x=True, expand_y=True, enable_click_events=True) layout = [[tbl1]] window = psg.Window("Table Demo", layout, size=(715, 200), resizable=True) while True: event, values = window.read() print("event:", event, "values:", values) if event == psg.WIN_CLOSED: break if '+CLICKED+' in event: psg.popup("You clicked row:{} Column: {}".format(event[2][0], event[2][1])) window.close()
It will produce the following output window −
The Table object also has an update() method to dynamically update the table properties such as values, num_rows, and row_color.
