Floating a div only when certain conditions are met

I have a .jsp that, based on parameters, can have 1 or 2 tables. If开发者_运维问答 only one of the parameters is fulfilled I want to have the table centered. If both parameters are fulfilled I want to float one table left and float the other table right. I can take care of the floating part, I am just unsure on how to have the other condition. I would think this can be done with some sort of 'if' statement....?

You'll most likely need to use a combination of <c:choose /> and <c:if />.

<c:choose>
  <c:when test="${conditionOne && conditionTwo}">
    <table class="tableLeft"></table>
    <table class="tableRight"></table>
  </c:when>
  <c:otherwise>
    <c:if test="${conditionOne || conditionTwo}">
      <table class="tableCenter"></table>
    </c:if>
  </c:otherwise>
</c:choose>

Hope this helps.
