我一起攻击了这个tab system。
我需要减少每个标签之间的间距（填充）。在firebug中查看时，你可以看到javascript函数在每个之间添加了各种左边的像素，但是不是随机填充左边的像素，我需要填充左边：每个标签之间100px。知道我该怎么做吗？
以下是javascript。
<script type="text/javascript">
var menuAlignment = 'left'; // Align menu to the left or right?
var topMenuSpacer = 0; // Horizontal space(pixels) between the main menu items
var activateSubOnClick = false; // if true-> Show sub menu items on click, if false, show submenu items onmouseover
var leftAlignSubItems = true; // left align sub items t
var activeMenuItem = false; // Don't change this option. It should initially be false
var activeTabIndex = 0; // Index of initial active tab (0 = first tab) - If the value below is set to true, it will override this one.
var rememberActiveTabByCookie = true; // Set it to true if you want to be able to save active tab as cookie
