Class SpanTag

java.lang.Object
  net.sf.jett.tag.BaseTag
      net.sf.jett.tag.SpanTag

All Implemented Interfaces:

Tag

public class SpanTag
extends BaseTag

A SpanTag represents a cell or merged region that will span extra rows and/or extra columns, depending on growth and/or adjustment factors. If this tag is applied to a cell that is not part of a merged region, then it may result in the creation of a merged region. If this tag is applied to a cell that is part of a merged region, then it may result in the removal of the merged region.

Attributes:

• Inherits all attributes from BaseTag.
• factor (optional): int
• adjust (optional): int
• value (required): RichTextString
• expandRight (optional): boolean

Either one or both of the factor and the adjust attributes must be specified.
