a column name can consist of a word, phrase or a numerical index; the intersection of a row and a column is called a cell. The elements of a table may be grouped, segmented, or arranged in many different ways, and even nested recursively. Additionally, a table may include metadata, annotations, a header, [6] a footer or other ancillary features ...
