ZK how to show 300 list header at one time

I have table with 30开发者_运维问答0 columns. I can show columns but zk tries to fit them on my current window. And each headers like inside others. Is there any way yo show headers with scroll bars? With fixed size like TOAD editor.

I solved my problem using like this

        <listbox id="listModel" rows="20"
                                    fixedLayout="true" span="true" mold="paging" pageSize="20">
                                    <listhead>
                                        <listheader id="${each}"
                                            label="${each}" width=" 250px"
                                            forward="onDoubleClick=onRemoveFromHeader"
                                            forEach="${comboModelColumns}" visible="false" />
                                        <custom-attributes
                                            headers="${each}" />


                                    </listhead>
                                    <listitem
                                        forEach="${listValues}">
                                        <listcell
                                            forEach="${listValues[forEachStatus.index]}"
                                            label="${each}" />
                                    </listitem>

                                </listbox>

But problem is I can see scrolbar-x on IE but on Firefox or Chrome it sets overflow hidden. Is there any way to fix it?

You can refer to the document about grid with hflex which is enhanced since ZK 5.0.6 version. To be honest, 300 columns shown in a grid seem not to be a good design for a user to navigate the grid, and it may cause some performance penalty.
