Package reahl.web.bootstrap.tables

New in version 3.2.

Tables are Widgets that show data items in rows arranged into aligned columns. This module includes tools to help transform data for display in a Table.

You can also display a Widget (such as a Button or Input) in a Table cell by using DynamicColumn.

The number of data items displayed in a Table can potentially be very large. DataTable solves this problem by only displaying a small portion of the data, allowing a user to page to different pages, each containing a suitably-sized smaller list. DataTable can also be set up to let a user sort data according to different columns.

Table

Examples

  • tutorial.tablebootstrap

Get a copy of an example by running:

reahl example <examplename>
class reahl.web.bootstrap.tables.Table(view, caption_text=None, summary=None, css_id=None)

Tabular data displayed as rows broken into columns.

Parameters:
  • view – (See Widget)
  • caption_text – If text is given here, a caption will be added to the table containing the caption text.
  • summary – A textual summary of the contents of the table which is not displayed visually, but may be used by a user agent for accessibility purposes.
  • css_id – (See HTMLElement)
with_data(columns, items)

Populate the table with the given data. Data is arranged into columns as defined by the list of DynamicColumn or StaticColumn instances passed in.

Parameters:
  • columns – The DynamicColumn instances that define the contents of the table.
  • items – A list containing objects represented in each row of the table.

DynamicColumn

class reahl.web.bootstrap.tables.DynamicColumn(make_heading_or_string, make_widget, sort_key=None)

DynamicColumn defines a logical column of a table, specifying how its heading will be rendered, and how the cell in this column will be displayed for each data item in the table.

Parameters:
  • make_heading_or_string – A string to be used as heading for this column, or a single-argument callable that will be called (passing the current view) in order to compute a Widget to be displayed as heading of the column.
  • make_widget – A callable that takes two arguments: the current view, and an item of data of the current table row. It will be called to compute a Widget to be displayed in the current column for the given data item.
  • sort_key – If specified, this value will be passed to sort() for sortable tables.

StaticColumn

class reahl.web.bootstrap.tables.StaticColumn(field, attribute_name, sort_key=None)

StaticColumn defines a column whose heading and contents are derived from the given field.

Parameters:
  • field – The Field that defines the heading for this column, and which will also be used to get the data to be displayed for each row in this column.
  • attribute_name – The name of the attribute to which field should be bound to on each data item when rendering this column.
  • sort_key – If specified, this value will be passed to sort() for sortable tables.

DataTable

class reahl.web.bootstrap.tables.DataTable(view, columns, items, css_id, items_per_page=10, caption_text=None, summary=None, table_layout=None)

A table containing a potentially large set of data items. DataTable does not display all its items on the current page. It renders as a table spread over different pages between which a user can navigate, thus preventing a large data set sent back to a single page.

If a DynamicColumn is used to define the table also specifies a sort_key, the table is rendered with controls on that column heading that allows it to be sorted on that column. The sort operation applies to the entire dataset even though the user stays on the current page and only sees a subset of that data.

Parameters:
  • view – (See reahl.web.fw.Widget)
  • columns – The DynamicColumn instances that define the contents of the table.
  • items – A list containing objects represented in each row of the table.
  • css_id – (See HTMLElement)
  • items_per_page – The maximum number of rows allowed per page.
  • caption_text – If given, a Caption is added with this text.
  • summary – If given, this text will be set as the summary of the contained Table (See Table).
  • table_layout – If given, the layout is applied to the contained Table.

TableLayout

class reahl.web.bootstrap.tables.TableLayout(inverse=False, border=False, compact=False, striped=False, highlight_hovered=False, transposed=False, responsive=False, heading_theme=None)

A Layout for customising details of how a Table is displayed.

Parameters:
  • inverse – If True, table text is light text on dark background.
  • border – If True, a border is rendered around the table and each cell.
  • compact – If True, make the table more compact by cutting cell padding in half.
  • striped – If True, colour successive rows lighter and darker.
  • highlight_hovered – If True, a row is highlighted when the mouse hovers over it.
  • transposed – If True, each row is displayed as a column instead, with its heading in the first cell.
  • responsive – If True, the table will scroll horizontally on smaller devices.
  • heading_theme – One of ‘inverse’ or ‘default’. An inverse heading is one with light text on a darker background.
