The widget shows a spreadsheet - either from XLS file or by setting the cell contents programmatically.
This version is very limited and should be considered to be "pre-alpha". Try out the demo to see if it would be useful for you. I mainly built it for an upcoming presentation.
SpreadsheetView class should be also usable in GWT without Vaadin Framework, but then you must implement SpreadsheetModel by yourself.
This is a "pre-alpha" quality release with severe limitations: • All columns and rows have fixed sizes • No cell styling is supported • No merged cells are supported • Performance for larger spreadsheets is really bad • Only one spreadsheet widget is supported on screen at once
