如何使二维数组迭代？

Question

我有一个table，我想通过它获取行和列坐标，喜欢它 table 有 Row-2 和 col-2

坐标 Row = [0,1] 和 Col = [0,1,0,1].

因为我将其存储在一个数组中，所以我想要一种更好的方法将其存储在二维数组中，以便如果 table 有超过 7 行和列，我可以迭代 it.Considering二维数组更好吗？

我写的方法存储在数组中，如何在其中制作一个二维数组？

CTable.prototype.GetTableMapping = function(currentTable)
{
    let oRowCount = currentTable.GetRowsCount();
    let oRowMapping = [];
    let oColumnMapping = [];
    let oTableMapping = [oRowMapping = [], oColumnMapping = []];
    for (let i = 0; i < oRowCount; i++)
    {
        let oRow = currentTable.GetRow(i);
        let oCellCount = oRow.GetCellsCount();
        oRowMapping.push(i);

        for (let j = 0; j < oCellCount; j++)
        {
            let oCell = oRow.GetCell(j);
            oColumnMapping.push(j);
        }
    }
    console.log("Table",oTableMapping);
    console.log("Rows",oRowMapping);
    console.log("Columns",oColumnMapping);
    return oTableMapping[oRowMapping,oColumnMapping];
};

Output:
[
   Row = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
   Cols = [0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3, 0, 1, 2, 3]
]

由于您已经有了双 for 循环，您可以使用它来创建二维单元格

arr2D[i][j] = oCell;

完整示例（模拟）：

mockTable = { // mocking the portions of your code that i don't know
  GetRowsCount : () => 11,
  GetRow: (x) => ({
    GetCellsCount : () => 4,
    GetCell : (x) => x
  })
}

CTable_prototype_GetTableMapping = function(currentTable)
{
    let oRowCount = currentTable.GetRowsCount();
    const arr2D = Array(oRowCount);
    //let oRowMapping = [];
    //let oColumnMapping = [];
    //let oTableMapping = [oRowMapping = [], oColumnMapping = []];
    for (let i = 0; i < oRowCount; i++)
    {
        let oRow = currentTable.GetRow(i);
        let oCellCount = oRow.GetCellsCount();
        arr2D[i] = Array(oCellCount);
        //oRowMapping.push(i);

        for (let j = 0; j < oCellCount; j++)
        {
            let oCell = oRow.GetCell(j);
            //oColumnMapping.push(j);
            arr2D[i][j] = oCell;
        }
    }
    //console.log("Table",oTableMapping);
    //console.log("Rows",oRowMapping);
    //console.log("Columns",oColumnMapping);
    return arr2D;
};

const theArray = CTable_prototype_GetTableMapping(mockTable);

console.log("cell (1,3)",theArray[1][3])
console.log("full 2D array", theArray)
