Spreadsheet is a rich ZK Component to handle EXCEL like behavior, it reads the data from a data model(SBook) and interact with this model by event.
You can assign a Book by setBook(Book) or just set the .xls file location by setSrc(String). You can also set two attributes to restrict max rows and columns to show on client side by setMaxVisibleRows(int) and setMaxVisibleColumns(int).
To use Spreadsheet in .zul file, just use <spreadsheet/> tag like any other ZK Components.
An simplest example :
;<spreadsheet src= "/WEB-INF/xls/my.xls" maxrows="300" maxcolumns="80"
height="400px" width="90%" />
