position:sticky is not supported in IE.
Have a look at the browser support at https://caniuse.com/#search=sticky

Maybe position:fixed is the solution as mentioned here : Position: sticky buttons not working in IE 11

Hope this would help.

The structure of my code is

<div>
     <table>
        <thead>
        <th></th>
        </thead>
      <tbody>
      </tbody>
 </div>

Header part of my code

<div class="box-body" style="width: 100%; display: inline-block; height: 636px; overflow: auto">
   <table class="table table-bordered table-striped table-fit table-fixed myBorderColor" style="width: 100%;">
       <thead>
           <th style="width: 15%; position: -webkit-sticky; position: sticky; top :0;">
               <spring:message code="my_label_name" />
           </th>
           <c:forEach items="${listForHeader[0].getListWeek()}"
               var="dayOfWeek" varStatus="week">
               <th colspan="3" class="text-center" style="position: -webkit-sticky; position: sticky; top: 0; ">
                   <c:if test="${dayOfWeek.week == 1}">
                       <spring:message code="my_label_monday" />
                       <br></br>
                       ${dayOfWeek.day}
                   </c:if> 
                   <c:if test="${dayOfWeek.week == 2}">
                       <spring:message code="my_label_tuesday" />
                       <br></br>
                       ${dayOfWeek.day}
                   </c:if> 
                   <c:if test="${dayOfWeek.week == 3}">
                       <spring:message code="my_label_wednesday" />
                       <br></br>
                           ${dayOfWeek.day}
                   </c:if>
                   <c:if test="${dayOfWeek.week == 4}">
                       <spring:message code="my_label_thursday" />
                       <br></br>
                       ${dayOfWeek.day}
                   </c:if> 
                   <c:if test="${dayOfWeek.week == 5}">
                       <spring:message code="my_label_friday" />
                       <br></br>
                       ${dayOfWeek.day}
                   </c:if>
                   <c:if test="${dayOfWeek.week == 6}">
                       <spring:message code="my_label_saturday" />
                       <br></br> 
                       ${dayOfWeek.day}
                   </c:if> 
                   <c:if test="${dayOfWeek.week == 7}">
                       <spring:message code="my_label_sunday" />
                       <br></br> 
                       ${dayOfWeek.day}
                   </c:if>
               </th>
           </c:forEach>
       </thead>

I want to fix this header as sticky so
I use style="width: 15%; position: -webkit-sticky; position: sticky; top :0;" in tag and
<div class="box-body" style="width: 100%; display: inline-block; height: 636px; overflow: auto">
it works in chrome But it does not work in Internet Explorer, also I tried out position: fixed,
but it also does not works in IE. Can you give some alternative to fix header.
