ROWS and COLUMNS
As mentioned previously, tables are a series of rows divided up into columns. A table with only one cell has one row and one column. The <TR> </TR> tags designate a table row. After starting the table with the opening <TABLE> tag, the next tag has to be the first row <TR>. Because a row or a column can use some of the same attributes, we will cover them together.
Once you have started a row, the next thing is to determine how many columns, or cells, that row will contain. A cell is defined by a table data tag <TD> </TD>. The fourth type of table tag is the table header <TH></TH>. The table header works the same as a table data tag, it just presents the text in a boldface. The text or contents of your table go between the table data <TD> </TD> and table header <TH> </TH> tags.
When you are designing your first tables, it may help to draw them out on paper first.
