The JSF Sheet Component is a JSF 2 component for the Primefaces Framework that wrappers the excellent Hansontable JavaScript component.
The project provides a JSF Spreadsheet component with the following features:
- Fast In-Cell Editing
- Copy/Paste
- Range Selection including Copy/Paste and Fill
- Sorting
- Filtering
- Fixed Columns and Rows
- Ajax Updates and Validation
To use the component, add the following dependency to your maven project:
<dependency>
<groupId>com.lassitercg</groupId>
<artifactId>jsf-sheet</artifactId>
<version>1.5</version>
</dependency>Add the XML namespace to your XHTML page:
xmlns:lcg="http://www.lassitercg.com/jsf"And use the component:
