How to create CellTable based on the response from the server

  1. I want to create a CellTable. But Columns of the celltable should be based on the response from the server. I'm getting the server response as List. 

    No of Columns = Size of the list.

  2. CellTable column header should be the value from the server. For ex. Server response: List<Contacts> contacts

    Header should be contacts.getName().

I achieved it by the following code.

          for (Contacts contact : contacts) {
               final String city = contact.getCity();
               final TextColumn<String> addressColumn = new TextColumn<String>() {

                @Override
                public String getValue(Contacts object) {
                    return city;
                }
            };

            cellTable.addColumn(addressColumn, contact.getAddress());
            }

Regards, Gnik

Use CellList with an AsyncDataProvider:

//Create a cellList
@UiField
CellList<Contact> cellList;

//Creating dataProvider and completion of the cellList
@UiFactory
CellList<Contact> makeCellList() {
private AsyncDataProvider<Contact> provider = new AsyncDataProvider<Contact>() {
    @Override
    public void onRangeChanged(final HasData<Contact> display) {
        rpcService.getContact(new AsyncCallback<List<Contact>>() {
               @Override
               public void onSuccess(List<Contact> result) {   
                   display.setRowData(0, result); 
               }
               @Override
               public void onFailure(Exception ex) {
                    //TODO
               }
        });
    }
};

//Adding the cellList to the provider in a constructor
provider.addDataDisplay(cellList);

Here's full example and docs.
