fun differentGame(row: Int, column: Int, player: String) {
val list: MutableList<MutableList<String>> = mutableListOf(
        mutableListOf("","","","",""),
        mutableListOf("","","","",""),
        mutableListOf("","","","",""),
        mutableListOf("","","","",""),
        mutableListOf("","","","",""),
        mutableListOf("","","","",""),
        mutableListOf("","","","",""),
        mutableListOf("","","","",""),
        mutableListOf("","","","","")
    )

    val iterator = list.iterator()
    while (iterator.hasNext()){
        val item = iterator.next()
        if (list.size > row){
            iterator.remove()
        } else break
    }
}

有这样的代码。在迭代器的帮助下，行被正常删除，但是如何删除或添加列？我试图通过标准 for 循环删除行和列，但它会在那里引发 ConcurrentModificationException。谷歌搜索并通过迭代器找到了异常的解决方案
