how to adjust extjs combo box width

[ragendu]

Hi,
I have a panel which has a couple of combo box and buttons. The first combo box is aligned to the left. I want to align that similar to those below. The button should also be adjacent to the combo. Below is the code.
I have attached the screen shot of the current panel.
Could some one please help me...

Thanks in advance...

filterPanel = new Ext.Panel({
renderTo: document.body,
bodyStyle: 'padding-top: 6px;',
title: 'Filters',

collapsed: true,
width: 450,
frame: true,
floating: true,
layout: 'form',
labelWidth: 150,
buttonAlign: 'center',

items: [
{
layout:'column',
items:[
{
columnWidth:.9 ,
layout: 'form',
items: [{
xtype:'combo',
id: 'xFilterEmail',
width: 250,
listWidth: 200,
fieldLabel: 'Filter by Owner',
store: emailStore,
displayField:'emailDisplay',
valueField:'emailValue',
triggerAction: 'all',
value: '<cfoutput>#trim(filterEmail)#</cfoutput>',
selectOnFocus:false
}]
},{
columnWidth:.1,
layout: 'form',
items: [{
xtype: 'button',
text: 'ME',
listeners: {
click: function(){
}
}]
}]
},{

If you want multiple components in a row you can use the fieldcontainer.
