DataFrame - to_latex() function

The to_latex() function is used to render an object to a LaTeX tabular environment table.

Syntax:

DataFrame.to_latex(self, buf=None, columns=None, col_space=None, header=True, index=True, na_rep='NaN', formatters=None, float_format=None, sparsify=None, index_names=True, bold_rows=False, column_format=None, longtable=None, escape=None, encoding=None, decimal='.', multicolumn=None, multicolumn_format=None, multirow=None)

Parameters:

Name	Description	Type/Default Value	Required / Optional
buf	Buffer to write to. If None, the output is returned as a string.	file descriptor or None	Required
columns	The subset of columns to write. Writes all columns by default.	list of label	Optional
col_space	The minimum width of each column.	int	Optional
header	Write out the column names. If a list of strings is given, it is assumed to be aliases for the column names.	bool or list of str Default Value: True	Required
index	Write row names (index).	bool Default Value: True	Required
na_rep	Missing data representation.	str Default Value: ‘NaN’	Required
formatters	Formatter functions to apply to columns’ elements by position or name. The result of each function must be a unicode string. List must be of length equal to the number of columns.	list of functions or dict of {str: function}	Optional
float_format	Formatter for floating point numbers. For example float_format="%%.2f" and float_format="{:0.2f}".format will both result in 0.1234 being formatted as 0.12.	one-parameter function or str, Default Value: None	Optional
sparsify	Set to False for a DataFrame with a hierarchical index to print every multiindex key at each row. By default, the value will be read from the config module.	bool	Optional
index_names	Prints the names of the indexes.	bool Default Value: True	Required
bold_rows	Make the row labels bold in the output.	bool Default Value: False	Required
column_format	The columns format as specified in LaTeX table format e.g. 'rcl' for 3 columns. By default, 'l' will be used for all columns except columns of numbers, which default to 'r'.	str	Optional
longtable	By default, the value will be read from the pandas config module. Use a longtable environment instead of tabular. Requires adding a usepackage{longtable} to your LaTeX preamble.	bool	Optional
escape	By default, the value will be read from the pandas config module. When set to False prevents from escaping latex special characters in column names.	bool	Optional
encoding	A string representing the encoding to use in the output file, defaults to 'utf-8’.	str	Required
decimal	Character recognized as decimal separator, e.g. ',' in Europe.	str Default Value: '.'	Required
multicolumn	Use multicolumn to enhance MultiIndex columns. The default will be read from the config module.	bool Default Value: True	Required
multicolumn_format	The alignment for multicolumns, similar to column_format The default will be read from the config module.	str Default Value: 'l'	Required
multirow	Use multirow to enhance MultiIndex rows. Requires adding a usepackage{multirow} to your LaTeX preamble. Will print centered labels (instead of top-aligned) across the contained rows, separating groups via clines. The default will be read from the pandas config module.	bool Default Value: False	Required

Returns: str or None
If buf is None, returns the resulting LateX format as a string. Otherwise returns None.
