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

dataSeries or DataFrame

Data to be styled - either a Series or DataFrame.

precisionint, optional

Precision to round floats to. If not given defaults to pandas.options.styler.format.precision.

Changed in version 1.4.0.

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, and falls back to pandas.options.styler.format.na_rep.

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, optional

Character used as decimal separator for floats, complex and integers. If not given uses pandas.options.styler.format.decimal.

New in version 1.3.0.

thousandsstr, optional, default None

Character used as thousands separator for floats, complex and integers. If not given uses pandas.options.styler.format.thousands.

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. If not given uses pandas.options.styler.format.escape

New in version 1.3.0.

formatterstr, callable, dict, optional

Object to define how values are displayed. See Styler.format. If not given uses pandas.options.styler.format.formatter.

New in version 1.4.0.

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


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.to_html 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
