The source code is based on the source for the Table and TreeTable components in the Vaadin Framework. Unlike the original Table this implementation does not have a page size. First it sends the whole table and later, if possible, only updates for changed, inserted or removed rows. Hence the name PMTable for "partial modification table" Not all features are kept from the original (e.g. Animation in TreeTable) and some features are not yet tested (e.g. generated rows). This implementation does not care about row height. So you can use rows with variable row height. On the other hand you can not yet scroll to a specific row (but by pixel). If you plan to use your own container, implement PMTable.PMTableItemSetChangeEvent or the whole table will be sent to the client on each change. When could PMTable be used: For a small table You want to fluently scroll the whole table. The table changes a lot. The table has variable row height You shouldn't use PMTable with large tables.
