Hi all,
i'm looking for add column on gridPanel.
With add method no firebug error appear but layout don't change.


var grid = new Ext.create('Ext.grid.Panel', {
title: 'List',
id: 'grid',
flex: 1,
store: 'storeGrid',
columns: [
new Ext.grid.RowNumberer(),
{
text: 'Prelievo',
flex: 1,
columns:[
{ header: "Label a", dataIndex: 'preA', flex:1},
{ header: "Delta", dataIndex: 'preB', flex:1}
]
}
]
});



var newCol = Ext.create('Ext.grid.column.Column', {
{
text: 'New Column',
flex: 1,
columns:[
{ header: "Label B", dataIndex: 'preC', flex:1},
{ header: "Delta", dataIndex: 'preD', flex:1}
]
}
});
grid.add(newCol);
grid.doLayout();

In your column object, your are adding an array of columns:

Try this:

Ext.create('Ext.data.Store', {
    storeId : 'simpsonsStore',
    fields  : ['name', 'email', 'change'],
    data    : {'items' : [
        { 'name' : 'Lisa',  'email' : 'lisa@simpsons.com',  'change' : 100  },
        { 'name' : 'Bart',  'email' : 'bart@simpsons.com',  'change' : -20  },
        { 'name' : 'Homer', 'email' : 'home@simpsons.com',  'change' : 23   },
        { 'name' : 'Marge', 'email' : 'marge@simpsons.com', 'change' : -11  }
    ]},
    proxy   : {
        type   : 'memory',
        reader : {
            type : 'json',
            root : 'items'
        }
    }
});

var grid = Ext.create('Ext.grid.Panel', {
    title      : 'Simpsons',
    store      : Ext.data.StoreManager.lookup('simpsonsStore'),
    columns    : [
        { header : 'Name', dataIndex : 'name' },
        { header : 'Email', dataIndex : 'email', flex : 1 },
        { header : 'Change', dataIndex : 'change'}
    ],
    height     : 200,
    width      : 400,
    renderTo   : Ext.getBody()
});

Ext.create('Ext.Button', {
    text: 'Click me',
    renderTo: Ext.getBody(),
    handler: function() {
        var column = Ext.create('Ext.grid.column.Column', {header: 'Column'});
        grid.headerCt.insert(grid.columns.length,column);
    }
});
