The ” <TR>” tag is used to define a table row. A row is made up of either table headers or table cells. Table rows are not allowed to directly contain data. Instead, table rows act as a container for the cells “<TD>” or the headers “<TH >” which contain data that is displayed in the table.
Question 25.
Why does not cTABLE width=100%> use the full browser width? (HOTS)
Answer:
Graphical browsers leave a narrow margin between the edge of the display area and the content.

If the document does not require scrolling, then this leaves a right ‘margin’ that cannot be removed.
