pyquickhelper.pandashelper.tblformat.df2rst(df, add_line=True, align='l', column_size=None, index=False, list_table=False, title=None, header=True, sep=', ', number_format=None)[source][source]

Builds a string in RST format from a dataframe.

Parameters

  • df – dataframe

  • add_line – (bool) add a line separator between each row

  • align – r or l or c

  • column_size – something like [1, 2, 5] to multiply the column size

  • index – add the index

  • list_table – use the list_table

  • title – used only if list_table is True

  • header – add one header

  • sep – separator if df is a string and is a filename to load

  • number_format – formats number in a specific way, if number_format is an integer, the pattern is replaced by {numpy.float64: '{:.2g}'} (if number_format is 2), see also pyformat.info>`__

Returns

string

If list_table is False, the format is the following.

None values are replaced by empty string (4 spaces). It produces the following results:

+------------------------+------------+----------+----------+
| Header row, column 1   | Header 2   | Header 3 | Header 4 |
| (header rows optional) |            |          |          |
+========================+============+==========+==========+
| body row 1, column 1   | column 2   | column 3 | column 4 |
+------------------------+------------+----------+----------+
| body row 2             | ...        | ...      |          |
+------------------------+------------+----------+----------+

If list_table is True, the format is the following:

.. list-table:: title
    :widths: 15 10 30
    :header-rows: 1

    * - Treat
      - Quantity
      - Description
    * - Albatross
      - 2.99
      - anythings
    ...

Changed in version 1.8: Parameter number_format was added.
