[4]: 114 A DataFrame is a 2-dimensional data structure of rows and columns, similar to a spreadsheet, and analogous to a Python dictionary mapping column names (keys) to Series (values), with each Series sharing an index. [4]: 115 DataFrames can be concatenated together or "merged" on columns or indices in a manner similar to joins in SQL.

Consecutive rows of column headers are top sticky, so avoid adding a row of headers right under the column headers that don't apply to the entire table such as a section header meant to visually separate the table. A solution might be to move each section to a column or separate tables, which also avoids accessibility issues per MOS:COLHEAD.
Template:Plain column headers/styles.css This template adds non-bolded and left-aligned column headers to tables, similar to the plainrowheaders class defined in common.css , which it can be used alongside.
