Examples of com.vaadin.ui.Table

com.vaadin.ui.Table

Table is used for representing data or components in a pageable and selectable table.

Scalability of the Table is largely dictated by the container. A table does not have a limit for the number of items and is just as fast with hundreds of thousands of items as with just a few. The current GWT implementation with scrolling however limits the number of rows to around 500000, depending on the browser and the pixel height of rows.

Components in a Table will not have their caption nor icon rendered.
