如何在 Tabulator JS 中將自訂格式化程式與預先定義格式化程式結合？

Question

我使用 Tabulator JS，並且有 2 列包含數字資料。首先，我使用了帶有formatterParams 參數的內建money 格式化程序，對於第二個，我想應用完全相同的、具有相同參數的，但還要添加，例如，單元格的顏色。如何以自訂格式套用formatterParams？

new Tabulator("#data-table", {
      data: data,
      layout: "fitColumns",
      columns: [{
          title: "Length",
          field: "length",
          formatter: zeroValueFormatter,
          formatterParams: {
            thousand: " ",
            precision: false
          }
        },
        {
          title: "New length",
          field: "newLength",
          formatter: "money",
          formatterParams: {
            thousand: " ",
            precision: false
          }
        ],
      });


function zeroValueFormatter(cell, formatterParams /* ? */) {
    if (cell.getValue() === 0) {
        cell.getElement().style.backgroundColor = "#add8e6";
    }    
    return cell.getValue();
}

一種選擇是使用 rowFormatter 並將格式套用到您需要的特定欄位。在您的範例中，是 length 列。這樣，您可以在兩列的列設定層級使用內建的 money 格式化程序，但在行層級套用其他格式。這是一個例子：

const data = [
  { length: 0, newLength: 10000 },
  { length: 2000, newLength: 20000 },
  { length: 3000, newLength: 0 }
]

const table = new Tabulator("#data-table", {
  data: data,
  layout: "fitColumns",
  rowFormatter: zeroValueFormatter,
  columns: [{
      title: "Length",
      field: "length",
      formatter: "money",
      formatterParams: {
        thousand: " ",
        precision: false
      }
    },
    {
      title: "New length",
      field: "newLength",
      formatter: "money",
      formatterParams: {
        thousand: " ",
        precision: false
      }
    }
  ],
});

function zeroValueFormatter(row) {
  const rowData = row.getData()

  if (rowData['length'] === 0) {
    row.getCell('length').getElement().style.backgroundColor = "#add8e6";
  }

}
