// xlsxTableParts directly maps the tableParts element in the namespace
// http://schemas.openxmlformats.org/spreadsheetml/2006/main - The table element
// has several attributes applied to identify the table and the data range it
// covers. The table id attribute needs to be unique across all table parts, the
// same goes for the name and displayName. The displayName has the further
// restriction that it must be unique across all defined names in the workbook.
// 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
// are displayed in the worksheet. The worksheet part has a separate element
// tableParts to store this information. Each table part is referenced through
// the relationship ID and again a count 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 created and stored the table part. For example:
//
//    <worksheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
//        ...
//        <tableParts count="1">
