arrays - knockout foreach add row number to grid -

-

i have grid fills array within array. creates according 1 array , fills column array.

like

 <div id="formula" data-bind="with:currentformula">         <!-- ko foreach:$parent.tones-->         <div class="col-sm-2" data-bind="foreach:$parents[1].levels">             <a href="#" class="thumbnail img-responsive" data-bind="click: $root.hascurrent() ? $root.currentformula().setending.bind($index(),$parentcontext.$index())  : $root.currentformula().setstarting.bind($index(),$parentcontext.$index())">                 <img data-bind="attr:{ src: '/content/images/colors/' +  $index() +  $parentcontext.$index() + '.png' }" alt="" />             </a>         </div>         <!-- /ko-->     </div>

what need create new column before col 1 , add $index() + 1, or row number work column.

i've looked on , have not found works.

how this?

from can tell, rows being created based on currentformula.tones within <!-- ko foreach:$parent.tones--> , columns based on tones.levels. should create div binds text $index() + 1 if first level (column). this, need move loop creating columns above div represent column.

something this:

<div id="formula" data-bind="with: currentformula">     <!-- ko foreach:$parent.tones-->         <!-- ko foreach:$parents[1].levels -->             <!-- if first level/column, create new column show rownum  -->             <div class="col-sm-2" data-bind="if: $index() == 0, text: 'row ' + $parent.$index() + 1"></div>             <!-- normal column creation -->             <div class="col-sm-2" >                 <a href="#" class="thumbnail img-responsive" data-bind="click: $root.hascurrent() ? $root.currentformula().setending.bind($index(), $parentcontext.$index()) : $root.currentformula().setstarting.bind($index(), $parentcontext.$index())">                     <img data-bind="attr: { src: '/content/images/colors/' + $index() + $parentcontext.$index() + '.png' }" alt="" />                 </a>             </div>         <!-- /ko-->     <!-- /ko--> </div>
