bokeh.models.widgets.tables¶
Various kinds of data table (data grid) widgets.
-
class
BooleanFormatter
(**kwargs)[source]¶ Bases:
bokeh.models.widgets.tables.CellFormatter
Boolean (check mark) cell formatter.
-
class
CellEditor
(**kwargs)[source]¶ Bases:
bokeh.model.Model
Abstract base class for data table’s cell editors.
Note
This is an abstract base class used to help organize the hierarchy of Bokeh model types. It is not useful to instantiate on its own.
-
class
CellFormatter
(**kwargs)[source]¶ Bases:
bokeh.model.Model
Abstract base class for data table’s cell formatters.
Note
This is an abstract base class used to help organize the hierarchy of Bokeh model types. It is not useful to instantiate on its own.
-
class
CheckboxEditor
(**kwargs)[source]¶ Bases:
bokeh.models.widgets.tables.CellEditor
Boolean value cell editor.
-
class
DataTable
(**kw)[source]¶ Bases:
bokeh.models.widgets.tables.TableWidget
Two dimensional grid for visualisation and editing large amounts of data.
-
columns
¶ property type:
List
(Instance
(TableColumn
) )The list of child column widgets.
-
editable
¶ property type:
Bool
Allows to edit table’s contents. Needs cell editors to be configured on columns that are required to be editable.
-
fit_columns
¶ property type:
Bool
Whether columns should be fit to the available width. This results in no horizontal scrollbar showing up, but data can get unreadable if there is no enough space available. If set to
True
, columns’ width is understood as maximum width.
-
header_row
¶ property type:
Bool
Whether to show a header row with column names at the top of the table.
-
index_header
¶ property type:
String
The column header to display for the index column, if it is present.
-
index_position
¶ property type:
Int
Where among the list of columns to insert a column displaying the row index. Negative indices are supported, and specify an index position from the end of the list of columns (i.e. standard Python behaviour).
To prevent the index column from being added, set to None.
If the absolute value of index_position is larger than the length of the columns, then the index will appear at the beginning or end, depending on the sign.
-
reorderable
¶ property type:
Bool
Allows the reordering of a tables’s columns. To reorder a column, click and drag a table’s header to the desired location in the table. The columns on either side will remain in their previous order.
-
scroll_to_selection
¶ property type:
Bool
Whenever a selection is made on the data source, scroll the selected rows into the table’s viewport if none of the selected rows are already in the viewport.
-
selectable
¶ property type:
Either
(Bool
,Enum
( Enumeration(checkbox) ) )Whether a table’s rows can be selected or not. Using
checkbox
is equivalent toTrue
, but makes selection visible through a checkbox for each row, instead of highlighting rows. Multiple selection is allowed and can be achieved by either clicking multiple checkboxes (if enabled) or using Shift + click on rows.

class
DateEditor
(**kwargs)[source]¶ Bases:

Format name(s) Format string Example Output ATOM

(ms since epoch) 1393632000000 Note that in the table some of the format names are synonymous, with identical format names separated by slashes.
This list of supported strftime format codes is reproduced below.
- %a
- The abbreviated name of the day of the week according to the current locale.
- %A
- The full name of the day of the week according to the current locale.
- %b
- The abbreviated month name according to the current locale.
- %B
- The full month name according to the current locale.
- %c
- The preferred date and time representation for the current locale.
- %C
- The century number (year/100) as a 2-digit integer.
- %d
- The day of the month as a decimal number (range 01 to 31).
- %D
- Equivalent to %m/%d/%y. (Americans should note that in many other countries %d/%m/%y is rather common. This means that in international context this format is ambiguous and should not be used.)
- %e
- Like %d, the day of the month as a decimal number, but a leading zero is replaced by a space.
- %f
- Microsecond as a decimal number, zero-padded on the left (range 000000-999999). This is an extension to the set of directives available to timezone.
- %F
- Equivalent to %Y-%m-%d (the ISO 8601 date format).
- %G
- The ISO 8601 week-based year with century as a decimal number. The 4-digit year corresponding to the ISO week number (see %V). This has the same format and value as %Y, except that if the ISO week number belongs to the previous or next year, that year is used instead.
- %g
- Like %G, but without century, that is, with a 2-digit year (00-99).
- %h
- Equivalent to %b.
- %H
- The hour as a decimal number using a 24-hour clock (range 00 to 23).
- %I
- The hour as a decimal number using a 12-hour clock (range 01 to 12).
- %j
- The day of the year as a decimal number (range 001 to 366).
- %k
- The hour (24-hour clock) as a decimal number (range 0 to 23). Single digits are preceded by a blank. (See also %H.)
- %l
- The hour (12-hour clock) as a decimal number (range 1 to 12). Single digits are preceded by a blank. (See also %I.) (TZ)
- %m
- The month as a decimal number (range 01 to 12).
- %M
- The minute as a decimal number (range 00 to 59).
- %n
- A newline character. Bokeh text does not currently support newline characters.
- %N
- Nanosecond as a decimal number, zero-padded on the left (range 000000000-999999999). Supports a padding width specifier, i.e. %3N displays 3 leftmost digits. However, this is only accurate to the millisecond level of precision due to limitations of timezone.
- %p
- Either “AM” or “PM” according to the given time value, or the corresponding strings for the current locale. Noon is treated as “PM” and midnight as “AM”.
- %P
- Like %p but in lowercase: “am” or “pm” or a corresponding string for the current locale.
- %r
- The time in a.m. or p.m. notation. In the POSIX locale this is equivalent to %I:%M:%S %p.
- %R
- The time in 24-hour notation (%H:%M). For a version including the seconds, see %T below.
- %s
- The number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC).
- %S
- The second as a decimal number (range 00 to 60). (The range is up to 60 to allow for occasional leap seconds.)
- %t
- A tab character. Bokeh text does not currently support tab characters.
- %T
- The time in 24-hour notation (%H:%M:%S).
- %u
- The day of the week as a decimal, range 1 to 7, Monday being 1. See also %w.
- %U
- The week number of the current year as a decimal number, range 00 to 53, starting with the first Sunday as the first day of week 01. See also %V and %W.
- %V
- The ISO 8601 week number (see NOTES) of the current year as a decimal number, range 01 to 53, where week 1 is the first week that has at least 4 days in the new year. See also %U and %W.
- %w
- The day of the week as a decimal, range 0 to 6, Sunday being 0. See also %u.
- %W
- The week number of the current year as a decimal number, range 00 to 53, starting with the first Monday as the first day of week 01.
- %x
- The preferred date representation for the current locale without the time.
- %X
- The preferred time representation for the current locale without the date.
- %y
- The year as a decimal number without a century (range 00 to 99).
- %Y
- The year as a decimal number including the century.
- %z
- The +hhmm or -hhmm numeric timezone (that is, the hour and minute offset from UTC).
- %Z
- The timezone name or abbreviation.
- %%
- A literal ‘%’ character.
Warning
The client library BokehJS uses the timezone library to format datetimes. The inclusion of the list below is based on the claim that timezone makes to support “the full compliment of GNU date format specifiers.” However, this claim has not been tested exhaustively against this list. If you find formats that do not function as expected, please submit a github issue, so that the documentation can be updated appropriately.

class
HTMLTemplateFormatter
(**kwargs)[source]¶ Bases:
bokeh.models.widgets.tables.CellFormatter
HTML formatter using a template. This uses Underscore’s template method and syntax. http://underscorejs.org/#template The formatter has access other items in the row via the dataContext object passed to the formatter. So, for example, if another column in the datasource was named url, the template could access it as:
<a href="<%= url %>"><%= value %></a>
To use a different set of template delimiters, pass the appropriate values for evaluate, interpolate’, or `escape. See the Underscore template documentation for more information. http://underscorejs.org/#template
Example: Simple HTML template to format the column value as code.
HTMLTemplateFormatter(template='<code><%= value %></code>')
Example: Use values from other columns (manufacturer and model) to build a hyperlink.
HTMLTemplateFormatter(template= '<a href="https:/www.google.com/search?q=<%= manufacturer %>+<%= model %>" target="_blank"><%= value %></a>' )
