pandas.io.formats.style.Styler

class pandas.io.formats.style.Styler(data, precision=None, table_styles=None, uuid=None, caption=None, table_attributes=None, cell_ids=True, na_rep=None, uuid_len=5, decimal='.', thousands=None, escape=None)

Helps style a DataFrame or Series according to the data with HTML and CSS.

Parameters

dataSeries or DataFrame

Data to be styled - either a Series or DataFrame.

precisionint

Precision to round floats to, defaults to pd.options.display.precision.

table_styleslist-like, default None

List of {selector: (attr, value)} dicts; see Notes.

uuidstr, default None

A unique identifier to avoid CSS collisions; generated automatically.

captionstr, tuple, default None

String caption to attach to the table. Tuple only used for LaTeX dual captions.

table_attributesstr, default None

Items that show up in the opening <table> tag in addition to automatic (by default) id.

cell_idsbool, default True

If True, each cell will have an id attribute in their HTML tag. The id takes the form T_<uuid>_row<num_row>_col<num_col> where <uuid> is the unique identifier, <num_row> is the row number and <num_col> is the column number.

na_repstr, optional

Representation for missing values. If na_rep is None, no special formatting is applied.

New in version 1.0.0.

uuid_lenint, default 5

If uuid is not specified, the length of the uuid to randomly generate expressed in hex characters, in range [0, 32].

New in version 1.2.0.

decimalstr, default “.”

Character used as decimal separator for floats, complex and integers

New in version 1.3.0.

thousandsstr, optional, default None

Character used as thousands separator for floats, complex and integers

New in version 1.3.0.

escapestr, optional

Use ‘html’ to replace the characters &, <, >, ', and " in cell display string with HTML-safe sequences. Use ‘latex’ to replace the characters &, %, $, #, _, {, }, ~, ^, and \ in the cell display string with LaTeX-safe sequences.

New in version 1.3.0.

DataFrame.style

Return a Styler object containing methods for building a styled HTML representation for the DataFrame.

Notes

Most styling will be done by passing style functions into Styler.apply or Styler.applymap. Style functions should return values with strings containing CSS 'attr: value' that will be applied to the indicated cells.

If using in the Jupyter notebook, Styler has defined a _repr_html_ to automatically render itself. Otherwise call Styler.render to get the generated HTML.

CSS classes are attached to the generated HTML

• Index and Column names include index_name and level<k> where k is its level in a MultiIndex

• Index label cells include

  • row_heading

  • row<n> where n is the numeric position of the row

  • level<k> where k is the level in a MultiIndex

• Column label cells include * col_heading * col<n> where n is the numeric position of the column * level<k> where k is the level in a MultiIndex

• Blank cells include blank

• Data cells include data
