使用 excel office 脚本将多个 table 中的特定列合并为一个 table

Question

正在寻找一种从多个 table 中按名称获取特定列的方法。我的数据来自多个 sheet，列数不同，最多 38 列，因此我无法使用 getColumnById。我只需要 7 列。

首先将所有 sheet 范围转换为 table，然后获取所有 table。我想要的是按名称获取特定列，然后在新的 sheet.

上将所有列合并为一个 table

我按照 Docs 中的示例进行了操作，但仍然无法获取每个 Table 的列名称。

我知道我的 header 值，如下例所示。

function main(workbook: ExcelScript.Workbook) {
    let sheets = workbook.getWorksheets();
    for (let sheet of sheets) {
        sheet.getTables()[0].convertToRange();
        sheet.addTable(sheet.getRange('A1').getUsedRange().getAddress(),true)
    }
    workbook.getWorksheet('Combined')?.delete();
    const newSheet = workbook.addWorksheet('Combined');
    const tables = workbook.getTables();
    const headerValues = [['Column1', 'Column6', 'Column8', 'Column9','Column11', 'Column16', 'Column18', 'Column19']];
    const targetRange = newSheet.getRange('A1').getResizedRange(headerValues.length - 1, headerValues[0].length - 1);
    targetRange.setValues(headerValues);
    const combinedTable = newSheet.addTable(targetRange.getAddress(), true);
    for (let table of tables) {
        let dataValues = table.getColumnByName( // this where am stuck //).getRangeBetweenHeaderAndTotal().getTexts();
        let rowCount = table.getRowCount();

        // If the table is not empty, add its rows to the combined table.
        if (rowCount > 0) {
            combinedTable.addRows(-1, dataValues);
        }
    }

}

感谢您的帮助。乔治

几件事：

在这种情况的大多数情况下，我建议迭代通过一组特定的 table 个对象。不幸的是，那是在这里很难做到。每次取消链接并重新创建新的 table， Excel 可能会给您的 table 一个新名字。这使得很难与 table 一起工作。您可以通过以下方式在代码中解决此问题在取消链接之前捕获 table 名称，取消链接 table，重新创建 table，并将 table 名称设置为原始名称捕获。如果你走那条路，那么你可以可靠地使用 table 个名字
因为 table 这种情况下的名字可能有点棘手，我要使用 sheet 名称，以便我可以使用包含的 sheets 底层 tables。这将允许我们使用和获取数据 tables 无论它们在 sheets 中的名称如何。

请看下面我的代码：

function main(workbook: ExcelScript.Workbook) {

//JSON object called SheetAndColumnNames. On the left hand side is the sheet name. 
 //On the right hand side is an array with the column names for the table in the sheet.

  //NOTE: replace the sheet and column names with your own values

  let columnNames : string[] = ["ColA","ColB","ColC"]
  const sheetAndColumnNames = {
    "Sheet1": columnNames,
    "Sheet2": columnNames
  }

//JSON object called columnNamesAndCellValues. On the left hand side is the column name. 
 //On the right hand side is an array that will hold the values for the column in the table.

//NOTE: replace these column names with your own values
  const columnNamesAndCellValues = {
    "ColA": [],
    "ColB": [],
    "ColC": []
  }


//Iterate through the sheetAndColumnNames object
  for (let sheetName in sheetAndColumnNames) {

//Use sheet name from JSON object to get sheet
      let sheet: ExcelScript.Worksheet = workbook.getWorksheet(sheetName)

//get table from the previously assigned sheet
      let table: ExcelScript.Table = sheet.getTables()[0]

//get array of column names to be iterated on the sheet
      let tableColumnNames: string[] = sheetAndColumnNames[sheetName]

//Iterate the array of table column names
      tableColumnNames.forEach(columnName=> {

//get the dataBodyRange of the tableColumn
        let tableColumn : ExcelScript.Range = table.getColumn(columnName).getRangeBetweenHeaderAndTotal()

//iterate through all of the values in the table column and add them to the columnNamesAndCellValues array for that column name
        tableColumn.getValues().forEach(value=>{
          columnNamesAndCellValues[columnName].push(value)
        })
      })
  }

  //Delete previous worksheet named Combined
  workbook.getWorksheet("Combined")?.delete()

  //Add new worksheet named Combined and assign to combinedSheet variable
  let combinedSheet : ExcelScript.Worksheet = workbook.addWorksheet("Combined")

  //Activate the combined sheet
  combinedSheet.activate()

//get the header range for the table
  let headerRange : ExcelScript.Range = combinedSheet.getRangeByIndexes(0,0,1,columnNames.length)

//set the header range to the column headers
  headerRange.setValues([columnNames])

  //iterate through the arrays returned by the columnNamesAndCellValues object to write to the Combined sheet
  columnNames.forEach((column,index)=>{
    combinedSheet.getRangeByIndexes(1, index, columnNamesAndCellValues[column].length, 1).setValues(columnNamesAndCellValues[column])
    })

  //Get the address for the current region of the data written from the tableColumnData array to the sheet
  let combinedTableAddress : string = combinedSheet.getRange("A1").getSurroundingRegion().getAddress()

  //Add the table to the sheet using the address and setting the hasHeaders boolean value to true
  combinedSheet.addTable(combinedTableAddress,true)
}
