code below:

<ext:TableLayout ID="TableLayout1" runat="server" Columns="3">
    <Cells>
        <ext:Cell>
            <ext:TextField ID="TextField1" runat="server" FieldLabel="Source" Width="300" LabelAlign="Right">
            </ext:TextField>
        </ext:Cell>
        <ext:Cell>
            <ext:Container ID="Container2" runat="server" Width="350">

                    <ext:ComboBox ID="ComboBox1" runat="server" FieldLabel="Type" Width="300" LabelAlign="Right"
                        Editable="false">
                    </ext:ComboBox>
                </Items>
            </ext:Container>
        </ext:Cell>
        <ext:Cell>
            <ext:Button ID="Button1" runat="server" Text="Search" Icon="Find">
                <Listeners>
                    <Click Fn="doQuery" />
                </Listeners>
            </ext:Button>
        </ext:Cell>
        <ext:Cell>
            <ext:DateField ID="DateField1" runat="server" Vtype="daterange" EndDateField="DateField2"
                FieldLabel="from" Width="300" LabelAlign="Right" Format="Y/m/d">
            </ext:DateField>
        </ext:Cell>
        <ext:Cell>
            <ext:DateField ID="DateField2" runat="server" Vtype="daterange" StartDateField="DateField1"
                FieldLabel="to" Width="300" LabelAlign="Right" Format="Y/m/d">
            </ext:DateField>
        </ext:Cell>
        <ext:Cell>
            <ext:Button ID="Button2" runat="server" Text="Reset" Icon="BinEmpty">
                <Listeners>
                    <Click Fn="clearQuery" />
                </Listeners>
            </ext:Button>
        </ext:Cell>
    </Cells>
</ext:TableLayout>
And another problem is FileUploadField can't display upload button in TableLayout.
