css+HTML表格高度

如何让表格内的div高度撑满整个td高度，表格内的td高度是可变的，不能设死高度像素

<template>
  <div id="printTable">
    <div class="Table">
      <div class="container">
        <table border="1px" cellspacing="0" class="text-center">

<style lang="scss" scoped>
.Table {
  width: 100%;
  margin: auto;
  background-color: #fff;
  // height: calc(100vh - 65px);
  height: 300px;

          th {

      tbody {
        tr {
          color: green;

          td {
            min-width: 100px;
            position: -webkit-sticky;
            position: sticky;
            word-break: break-word;
            word-wrap: break-word;
          }
        }
      }

    }
  }

}

.layar{
  border-right: 1px solid #000;
}
.layar:last-child{
  border-right: none;
}
</style>

td有高度的话，可以给div的高度给100%
