tablecell

A table cell, or tablecell, is the basic unit at the intersection of a row and a column in a tabular structure. It holds individual data values or header information and forms the building block of a table's grid.

In HTML, table cells are represented by the td element for data cells and the th element for header cells, which are placed inside a row element (tr) within a table, or inside sections such as thead, tbody, and tfoot. A cell can span multiple columns or rows using colspan and rowspan attributes. The th element typically conveys semantic meaning and can improve accessibility when paired with scope or headers attributes.

In CSS and other rendering contexts, table cells are treated as elements with display: table-cell, and their appearance can be controlled with padding, borders, vertical alignment, and width.

In spreadsheets and database software, a table cell refers to a single grid position that can contain numbers, text, formulas, or references. The contents may depend on the software's data types and formatting options.

Accessibility considerations emphasize using semantic header cells and associating header cells with data cells via id-based references or the scope attribute to aid screen readers.
