You would then merge the table data into the document- which would produce one envelope for each record in the table.
In this example, you would create a single envelope document and place a field for the customer name and another field for the customer address on the face of the envelope. For example, if you had a table that contained the names and addresses of your customers, you could create a document, like an envelope for example, that would display the name and address of each customer on its face. For each record, or row, within the table, you will typically produce one copy of the document. You can use the features in Word’s “Mailings” tab in the Ribbon to perform automated mailings, often referred to as performing a “mail merge.” When you use the mail merge feature in Word, you merge information from a table, called a “data source,” into designated fields in your document.
