Как мне сделать прозрачный border у таблицы?

body {
  background-color: #27214b;
}

:root {
  --br: 18px;
  --bc: blue;
}

.table-statistic {
  border-spacing: 0;
}

.table-statistic td {
  padding: 5px 10px;
  border-top: 0;
  border-bottom: 0;
}

.table-statistic thead th:first-child {
  border-top-left-radius: var(--br);
}

.table-statistic thead th:last-child {
  border-top-right-radius: var(--br);
}

.table-statistic tbody tr:last-child td {
  border-bottom: 1px solid var(--bc);
}

.table-statistic tbody td:first-child {
  border-left: 1px solid var(--bc);
}

.table-statistic tbody td:last-child {
  border-right: 1px solid var(--bc);
}

.table-statistic tbody td:not(:last-child) {
  border-right: 1px solid white;
}

.table-statistic tbody tr:last-child td:first-child {
  border-bottom-left-radius: var(--br);
}

.table-statistic tbody tr:last-child td:last-child {
  border-bottom-right-radius: var(--br);
}
