In relational databases, and flat file databases, a table is a set of data elements (values) using a model of vertical columns (identifiable by name) and horizontal rows, the cell being the unit where a row and column intersect. Besides the actual data rows, tables generally have associated with them some metadata, such as constraints on the table or on the values within particular columns. In many systems for computational statistics, such as R and Python 's pandas, a data frame or data table is a data type supporting the table abstraction.
Since many tables use the top row for header information, html also supports a th tag used to define the cells in the header row. For example, a relation with two attributes and three values can be represented as a table with two columns and three rows, or as a two-dimensional graph with three points.
