Class Row

public class Row extends Object implements Element

A Row is part of a Table and contains some Cells.

All Rows are constructed by a Table-object. You don't have to construct any Row yourself. In fact you can't construct a Row outside the package.

Since a Cell can span several rows and/or columns a row can contain reserved space without any content.
