creating a scroll box on left side of page with data while right stays in place and displays results on right when clicked

issues with <v-data-table and <td. New at this and trying to learn but not finding much help. I saw there is <v-virtual-scroll but that throws td off and gives an error saying no end. I can’t give much more than this unfortunately

    <v-col cols=""
     <div class= *code*</div>
     <div class=*code*</div>
     <v-divider></v-divider>
     <v-data-table
         *code*
      <template v-slot:[`item`] = *code*
       <tr :class=isSelected ? *code*
        <td class=""
         <v-row no gutters>
          <v-col cols="">
          <span>
