Form

Tables are defined by tags. Each table has several rows (defined by tags), and each row is divided into cells (defined by tags). The letter td refers to tabular data (table data), that is, the contents of data cells. Data cells can contain text, pictures, lists, paragraphs, forms, horizontal lines, tables, and so on.

Table and Border Properties

Use the border properties to display a table with borders:

The header of the form

The header of the table is defined with a label.

Empty cells in a table

Table cells without content do not display very well in some browsers. If a cell is empty (with no content), the browser may not be able to display the border of the cell. The border of the empty cell is not displayed. To avoid this, add a space placeholder to the empty cell to display the border.
