extjs4(include 4.2) table layout lost its item in ie8

[DazzlingBeing]

this is happend only in ie8.
when change the table's layout column, item in the column disappeared.
This is a very simple page, I create a view with table layout, and then put 8 buttons in it, then I add a resize listener to dynamiclly change the table's column.
Open the page in ie8 with fullscreen, and change the ie8's size smaller, then some buttons disappeared.Check the html source, the disappeared buttons' dom are deleted.
Source to test this:
Ext.onReady(function() {

var items = [];

for (var i = 1; i <=8; i++) {

items.push({

xtype: 'button',
width: 200,
text: 'button' + i

});

}

Ext.create('Ext.container.Viewport', {

layout: {

type: 'table',
columns: 1

},
items: items,
listeners: {

resize: function(comp, width, height, oldWidth, oldHeight) {

var columns = Math.floor(width/200);alert(columns);
if (columns != comp.layout.columns) {

comp.layout.columns = columns;
comp.updateLayout();

}

}

},
renderTo: Ext.getBody()

});

});

Thanks for the report! I have opened a bug in our bug tracker.

Track the source of Ext.layout.container.Table.js,
in the function 'renderChildren' I found:

// If at the end of a row, remove any extra cells

if (!cells[i + 1] || cells[i + 1].rowIdx !== rowIdx) {

cellIdx++;

while (trEl.cells[cellIdx]) {

trEl.deleteCell(cellIdx);

}

}

when call the method 'deleteCell', the dom has been delete from the dom tree, so when call 'me.moveItem(item, itemCt, 0);', the item.el.dom is ''.

is that the ie8's feature or bug?
