Layout issue: Show Gridpanel in gridpanel with rowexpander

[Daniil]

I was able to align header via applying the following css rules.

Css rules to fix

.x-grid3-row td {
    padding-left: 0px;
    padding-right: 0px;
}

Also the GridView's ScrollOffset property can help you to get a grid looks better.

Seems you have missed this recommendation:)

I have took your code, applied these css rules and it appears to be working fine.
