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)

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

Parameters:

data : Series or DataFrame

precision : int

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

table_styles : list-like, default None

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

uuid : str, default None

a unique identifier to avoid CSS collisions; generated automatically

caption : str, default None

caption to attach to the table

cell_ids : bool, 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.

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 * evel<k> where k is the level in a MultiIndex
• Blank cells include blank
• Data cells include data
