data tables with headers, footers and widgets in cells

[Matthew Pocock]

Hi,

I'm developing an app that needs to display some info in a grid/table. It needs to support pinned headers/footers, paging, sorting, filtering, scrolling of the non-header/footer cells, and individual cells are custom widgets that are constantly listening to events and updating and/or which have custom editors attached.

I started off building on FlexTable, and this let me get all the custom, interactive cell behaviour working. However, it doesn't support any of the column operations or the header/footer and scrolling stuff. DataGrid seems to support the inverse - it does most of what I need but cells are not widgets.

What's the solution?

Thanks,

Matthew

The DataGrid will be able to do everything that you want, here is the link for the GWT Showcase of it: http://gwt.google.com/samples/Showcase/Showcase.html#!CwDataGrid

As you can see, you can have widgets inside of the cells.

For a better example of different widgets inside the cells you can look at: http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellSampler

Joshua is right: DataGrid is your solution. If existing cells do not meet your needs, you can build any cell you like by extending AbstractCell.

Thanks. I've cobbled something together with DataGrid.

I've had a proper look at the cell sampler showcase. While it does render UI components for cells, it isn't actually embedding widgets. It's using classes like CheckboxCell that render html directly. So it doesn't look like with this approach I can embed my custom IsWidget directly as cell content.

What do you want to embed in your cells? I may give you some pointers.
