：js按table某列的內容進行排序并該列內容次數越少越排后

function sortTableByColumn_count(myTable, columnIndex, isNumber) {

const table = document.getElementById(myTable);

var tbody = table.tBodies[0];

  var rows = Array.from(tbody.rows);

  var firstRow = rows.shift();

  tbody.deleteRow(0); // 移除原始的表頭

  table.insertBefore(firstRow, tbody); // 將表頭重新添加到表格

  rows.sort(function(a, b) {

    var cellA = a.cells[columnIndex];

    var cellB = b.cells[columnIndex];

    if (isNumber) {

      return parseFloat(cellA.textContent) - parseFloat(cellB.textContent);

    } else {

      return cellA.textContent.localeCompare(cellB.textContent);

    }

  });

  // 計算每個數值出現的次數

  var counts = rows.reduce(function(counts, row) {

    var value = row.cells[columnIndex].textContent;

    counts[value] = (counts[value] || 0) + 1;

    return counts;

  }, {});

  // 根據出現次數倒序排序

  rows.sort(function(a, b) {

    return counts[b.cells[columnIndex].textContent] - counts[a.cells[columnIndex].textContent];

  });

  for(var i = 0; i < rows.length; i++) {

    tbody.appendChild(rows[i]);

  }

}
