A simple configurable table widget based on PyQt5 and pandas

How to use

Get version

from pyqttable import version

print(version.VERSION)

Create table

from pyqttable import PyQtTable

table_widget = PyQtTable(
    parent=None,              # parent widget
    column_config=my_config,  # column configurations
    show_filter=True,         # show filter in header
    sortable=True,            # sortable column (triggered by right click)
    draggable=True,           # draggable column
)

Column Config

A list of configurations for each column

Config Key	Description	Value Type	Default Value
key	key of column (used to access data from DataFrame)	str	# required
name	column name to display	str	# same as key
type	column value type (required for conversion between real value and string)	# see Column.Type	str
editable	controlling the cell value is read-only or not	bool	True
default	default value when key is missing in data (not recommended)	-	None
h_align	horizontal alignment	# see Column.Align	'l'
v_align	vertical alignment	# see Column.Align	'c'
selection	list of valid values	list	None
sort_lt	DIY __lt__ methods for sorting (only effective when sortable is True)	# see Column.Sort	None
filter_type	filter type (only effective when show_filter is True)	# see Column.Filter	'contain'
color	font color (in string or tuple indicating RGB)	# see Column.Color	None
bg_color	background color (same format as color)	# see Column.Color	None

Example

{
    'key': 'gender',                        # same as DataFrame column
    'name': 'Gender',                       # shown as table header
    'type': str,                            # string variable
    'editable': False,                      # read-only
    'selection': ['male', 'female'],        # could be either 'male' or 'female'
    'h_align': 'r',                         # align right
    'sort_lt': lambda x, y: x == 'female',  # 'female' < 'male'
    'filter_type': 'multiple_choice',       # multiple-choice filter
    'bg_color': (135, 206, 250)},           # blue opaque background
}

Column.Type

Column type should be following class (not instance)

Column type
int
float
str
bool
datetime.datetime
datetime.date
datetime.time

Column type can also be instance of ColumnType Inherit from ColumnType to make DIY column type Inherit from EditorFactory to make DIY editor for DIY column type (if required)

from pyqttable.column import type_
from pyqttable.editor import EditorFactory

class MyEditorFactory(EditorFactory):
    ...

class MyColumnType(type_.ColumnType):
    EditorFactory = MyEditorFactory()
    ...

Column.Align

Key	Valid value	Flag
h_align	'l' / 'left'	AlignLeft
h_align	'r' / 'right'	AlignRight
h_align	'c' / 'center'	AlignHCenter
v_align	't' / 'top'	AlignTop
v_align	'b' / 'bottom'	AlignBottom
v_align	'c' / 'center'	AlignVCenter

Column.Color

Value type	Value format
str	'#RRGGBB'
Tuple[int]	(R, G, B, Optional[T])

Column.Filter

Column filter type should by following string

Filter type
'exact'
'contain'
'expression'
'regex'
'multiple_choice'

Column filter type can also be instance of Filter Inherit from Filter to make DIY filter type

from pyqttable.column import filter_

class MyFilterType(filter_.Filter):
    ...

Column.Sort

Sorting is triggered by right click on headers Variable sort_lt should be a function with same signature as __lt__ When sort_lt is defined, sorting action will based on sort_lt instead of default __lt__

How to set data

import pandas as pd
my_data = pd.DataFrame(...)
table_widget.set_data(my_data)

How to get data

my_data = table_widget.get_data(data)
shown_data = table_widget.get_data(data, full=False)

How to get filter data

current_filter_dict = table_widget.get_filter_data()
