## com.lowagie.text
Class Row

    java.lang.Object
      com.lowagie.text.Row

All Implemented Interfaces:
  Element

    public class Row

extends java.lang.Object
implements Element

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

All `Row`s 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.

See Also:
  `Element`, `Cell`, `Table`

Field Summary
`static int` `CELL` id of the Cell element in a Row
`protected java.lang.Object[]` `cells` This is the array of Objects (`Cell` or `Table`).
`protected int` `columns` This is the number of columns in the `Row`.
`protected int` `currentColumn` This is a valid position the `Row`.
`protected int` `horizontalAlignment` This is the vertical alignment.
`static int` `NULL` id of a null element in a Row
`protected boolean[]` `reserved` This is the array that keeps track of reserved cells.
`static int` `TABLE` id of the Table element in a Row
