Ext GWT Grid, Grid Plugins, and EditableGrid

Darrell Meyer has posted a preview of the Ext GWT Grid and more.

Ext GWT 1.1 development is moving along nicely and includes a new Grid component. Grid is based on the Ext JS Grid and will support the same features including grid plugins, grouping, totaling, and inline editing.

Grid vs. Table

One if the biggest differences between Table and Grid is performance. Table does not scale well with a large number of rows. Grid renders its data much faster and can handle larger data sets with noticeable differences in initial rendering times.

Table is a container of TableItems which work without a model. TableItems deal directly will cell values. Model support is added using a TableBinder which works with a Store. With Grid, there are no child components and Grid works with the Store directly. This design simplifies use and the binder is no longer needed.
