title: get serial number in reverse order in vue js
body: <p>below is the code for displaying serial number while iterating list.
  now i cant sort the list due to some reasons and the list will be as it is.
  but i want serial number to be printed in reverse order. If size of array is 5 i need 5 4 3 2 1.    </p>
  
  <pre><code>&lt;table class="table" border=1 width="650" style="word-wrap:break-word"&gt;
           &lt;tr&gt;
            &lt;td colspan="6" class="heading"&gt;
              &lt;b&gt;Corrigendum Document Details&lt;/b&gt;
            &lt;/td&gt;
          &lt;/tr&gt;
                &lt;tr&gt;
                  &lt;th align="center" style="width:7.5%"&gt;Corr.No.&lt;/th&gt;
                  &lt;th align="center"&gt;Corrigendum Title&lt;/th&gt;
                  &lt;th align="center"&gt;Corrigendum Description&lt;/th&gt;
                  &lt;th align="center"&gt;Published Date&lt;/th&gt;
                  &lt;th align="center"&gt;Document Name&lt;/th&gt;
                  &lt;th align="center"&gt;Doc Size(in KB)&lt;/th&gt;
                &lt;/tr&gt;
                &lt;tr v-for="(corrworkdoc,index) in corrWorkItemDocumentsAndCorrDetailList" i = index&gt;
                  &lt;td&gt;{{index+1}}&lt;/td&gt;
                  &lt;td&gt;{{corrworkdoc.corrigendumTitle}}&lt;/td&gt;
                  &lt;td&gt;{{corrworkdoc.corrigendumDescription}}&lt;/td&gt;
                  &lt;td&gt;{{corrworkdoc.publishedDate}}&lt;/td&gt;
                  &lt;td&gt;&lt;a href="#" v-on:click="doDownload(corrworkdoc.fileName)" title="Download" style="color:blue;"&gt;{{corrworkdoc.fileName}}&lt;/a&gt;&lt;/td&gt;
                  &lt;td&gt;{{corrworkdoc.docSize}}&lt;/td&gt;
                &lt;/tr&gt;
      &lt;/table&gt;
