// Later on we will see that you can define names for many elements, such as
// cells or formulas. The name value is used for the object model in Microsoft
// Office Excel. The displayName is used for references in formulas. The ref
// attribute is used to identify the cell range that the table covers. This
// includes not only the table data, but also the table header containing column
// names.
// To add columns to your table you add new tableColumn elements to the
// tableColumns container. Similar to the shared string table the collection
// keeps a count attribute identifying the number of columns. Besides the table
// definition in the table part there is also the need to identify which tables

// maintained. The following markup sample is taken from the documents
// accompanying this book. The sheet data element has been removed to reduce the
