Struggling to find the right look for identical items

I'm currently working on a project where I need to identify and hide duplicate values in a table. The goal is to only display unique values in the first column and hide any duplicates from view. However, I'm running into an issue when trying to hide the duplicates using the display style attribute set to "none". Below is the code I am using:

Thank you in advance, PD

 var data=[['e',0,1,2,3,4], ['a',54312,235,5,15,4], ['a',6,7,8,9,232],
     ['a',54,11235,345,5,6], ['b',0,1,2,3,4], ['b',54312,235,5,15,4],
     ['c',62,15,754,93,323], ['d',27,11235,425,18,78], ['d',0,1,2,3,4],
     ['d',54312,235,5,15,4], ['e',6,7,8,9,232], ['e',54,11235,345,5,6],
     ['e',0,1,2,3,4], ['e',54312,235,5,15,4], ['e',62,15,754,93,323], 
     ['e',27,11235,425,18,78]];


 //Creating an HTML Table element.
     var table = document.createElement("TABLE");
     var somedata = document.createElement("TD");
     var dvTable = document.getElementById("dvTable");
     var elems = document.getElementsByClassName("tableRow");


  //Finding the count of columns.
  var columnCount = data[0].length;

    //Adding the data rows.  
   for (var i = 0; i < data.length; i++) {  
   var row = table.insertRow(-1);
      for (var j = 0; j < columnCount; j++) {

            var dup =  data[otherRow][0];
               console.log("What is the dup" + dup);
            if (num === dup)
            { 
                 console.log("duplicate");
                 dvTable[i].style.display = "none";
            }
         }


            var cell = row.insertCell(-1);                    
            cell.innerHTML = data[i][j];
            cell.innerHtml = myZero; 



      }     
   }

dvTable represents an HTML table element. It is not possible to retrieve rows using dvTable[i].

Consider the following alternative method -

dvTable.rows(i).cells(j).style.display = none;
