4. What does <td> stand for?
a) Table directory
b) Table direct row
c) Table database

5. How does indenting the code for a table be helpful?
a) One tag in a table can prevent the entire table from being displayed properly
b) It helps in providing the updated data regularly
c) No, indenting the code can increase the complexity of the table
d) Indenting helps in better indexing

Explanation: Many web page authors find it particularly helpful to indent the code for a table because leaving off just one tag in a table can prevent the entire table from being displayed properly. Indenting the code makes it easier to keep track of the opening and closing of each element.
6. How are <td> and <th> used in a table?
a) Each cell must be represented by either a <td> or a <th> element
b) Only represented by <td> when the table data is present
c) Only represented by <th> when the header is present
d) <td> and <th> can be ignored in respective exceptional cases
View Answer
Explanation: Every cell must be represented by either a < td > or a < th > element for the table to display correctly, even if there is no data in that cell. If a row or column should contain a heading, a < th > element should be used in place of the < td > element for the cells that contain a heading.
7. You cannot have an opening tag for an element inside a table cell and a closing tag outside that cell, or vice versa?
a) True

View Answer
Explanation: The only constraint on placing markup inside a table is that it must nest within the table cell element (be that a < td > or a < th > element). When creating tables, many people do not actually bother with the < th > element and instead use the < td > element for every cell, including headers.
