What are table headers and scopes?

To understand the process of making tables accessible, it is easiest to cover the basic parts of a table first. Each cell in a table is defined by a tag. This cell conveys no relationship to any other cell in the table unless one is defined. Making a cell into a table header means that that cell describes other cells in the table, but does not say if it describes the cells below it, or to the side. Adding a scope to that header, such as scope=”row” or scope=”col”, defines if the header is for a row header for describing cells to the right of the cell, or a column header which describes cells below it. Each time a header cell is defined, a scope should be used as well. For a detailed explanation and an example on how to fix these problems, see Checkpoint G.
