| Table creation starts with the table tag <table>, then we define the border.
The border of this table is 1 and the caption is default, which is
top-centered. No cellspaces or cellpadding were specified.
A row of heading was defined using table row <tr> and table heading <th> tags.
Then three more rows of data were created using table row and table data <td> tags. Each tag closes when it's content ends. Result
