No. Create a table for each unique type of entity in your system: a Customer, perhaps an Address, an Item for sale, and an Order. Then create a table for each one to many relationship in the system. An Order contains many Items, so you need an Order_Items table.
Then to add an order, find the Customer's id (creating a Customer or using an existing one). Create a new Order. Add a row to the Order_Items table for each Item in the Order.
Every unique entity in the system should occur only once in the system. That's basically the normalization rule to go by.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
