Question

I’m fairly new to ExtJS. I adopted some examples and added the functionality to add tabs to a tab-control by clicking on some link. so far so good. Now I want to load a ExtJS table into on of the new tabs. the items (rows, columns) are defined in a database on the server side. Can you give me some hints how to add the table automatically when the tab is created?

Autoload is good for pulling an HTML table from your server-side code. Does this data ever get updated? If so you will need to reload the entire HTML. I would suggest using a grid instead:

    // tabPanel definitinon
    {
        xtype:"grid",
        //tabId is a unique value created at the time of the tab
        id:"general_props_status_grid_" + tabId,
        ds: C.createStore({
            storeId:"general_props_status_grid_" + tabId,
            autoLoad:true
            proxy: new Ext.data.HttpProxy({
                //path to a serverside page that gerenates a JSON table contents
                url: '?fuseaction=qry_statuses'
            }),

            reader: new Ext.data.JsonReader({
                id: 'status_id',
                root:'data'
            }, [
                {name: 'status_id'},
                {name: 'name'}
            ]),
            remoteSort: false
        }),
        columns:[{
            header: "Status ID",
            dataIndex: 'status_id',
            width:20,
            hidden:true,
            sortable:true
        },{
            header: "Name",
            dataIndex: 'name',
            hideable:false,
            renderer:function(val){
                return "<span class='link'>" + val +"</span>"
            },
            width:150,
            sortable:true
        }],
        sm: new Ext.grid.RowSelectionModel({singleSelect:true}),
        loadMask: true,
        listeners: {
            activate:function(thisGrid){
                //this will reload the grid each time this tab is selected
                thisGrid.getStore().reload();
            }
        }
    }

There are a ton of options for grids, but the above example shows an automatically updating grid via callbacks.
