Google sheets GoogleSheets：基于单元格的COUNTA重复一行，ARRAYFORMULA

我有一张如下的桌子。该表会不时更新，因此不知道确切的行数：

+--+-------+-------------+
|a |红色| 1,1,1,|
+--+-------+-------------+
|b |绿色| 2,2,|
+--+-------+-------------+
|c |蓝| 3|
+--+-------+-------------+

在脚本编辑器中粘贴此脚本

    /** 
 * Splits the array by commas in the column with given index, by given delimiter
 * @param {A2:B20}  range Range reference
 * @param {2}  colToSplit Column index
 * @param {","}  delimiter Character by which to split
 * @customfunction
 */


function advancedSplit(range, colToSplit, delimiter) {
    var resArr = [], row;
    range.forEach(function (r) {
        r[colToSplit-1].replace(/(?:\r\n|\r|\n)(\d|\w)/g,", ").split(delimiter)
            .forEach(function (s) {
                row = [];
                r.forEach(function (c, k) {               
                   row.push( (k === colToSplit-1) ? s.trim() : c);
                })
                resArr.push(row);
            })
    })
     return resArr.filter(function (r) {
        return r.toString()
            .replace(/,/g, "")
    })
    }

然后在电子表格中将此脚本用作自定义公式

=advancedSplit(E2:G, 3, ",")

我希望这有帮助？
