// define names for many elements, such as cells or formulas. The name

// 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.

// tableColumns container. Similar to the shared string table the

// of the number of table parts is maintained. The following markup sample
// is taken from the documents accompanying this book. The sheet data
// element has been removed to reduce the size of the sample. To reference
// the table, just add the tableParts element, of course after having
