The best way to illustrate this is to take a ruler, hold it to the screen displaying the page and draw it down the page one line at a time. If the page displays information in a number of columns it can be very confusing when read allowed. Most of these problems can be overcome simply by constructing the HTML tables correctly and only using these tables at appropriate times. HTML editors are not as useful at creating tables as those that show the HTML tags. A good background knowledge of HTML is essential to avoid common mistakes.
Many elements go into the construction of HTML tables.
The following sections cover the basic attributes that should always be included to format a table. This is the tag that establishes the table within the HTML document. As soon as a browser reads this tag it knows that everything included after it that is contained within cells is to be constructed in a tabular format. Any value added to this attribute will affect the dimensions of the border surrounding the tabular information. This value can be any pixel value from zero upwards.
