Android listOf(listOf(字符串))在lazyArchitect(lazyStream)中合成

目前只有外部列表触发重组.当内部列表中的字符串也被更改/添加时，如何触发重新组合？

private var data by mutableStateOf<List<List<StringObject>>>(
    // Initialize with some sample data (20 rows, 10 columns)
    List(20) { outerIndex ->
        List(10) { innerIndex ->
            val value = "Value ${outerIndex * 10 + innerIndex + 1}"
            val imageUrl = if (innerIndex % 2 == 0)
                "https://example.com/image${innerIndex + 1}.jpg"
            else
                null
            StringObject(value, imageUrl)
        } as List<StringObject>
    }
)

我try 更换这个

mutableStateOf<List<List<StringObject>>>

用这个:

mutableStateOf<List<MutableList<StringObject>>>

但这会导致应用程序因并发修改而崩溃.我是作曲的新手，老实说，由于所有这些不可变和状态的东西，它很糟糕.新语言应该自己在内部管理这些东西.

既然不可变列表不允许我在其中添加内容，该如何处理它？制作可变副本似乎资源成本高昂，尤其是如果您拥有一个大规模的列表数据列表.

Update 1- 这是当前的addStream函数

private fun addColumn() {
    data.withIndex().forEach { (index, row) -> // Use data.withIndex().forEach
        data[index].plus(ExcelCell("")) // Directly modify data
    }
}

重组仍未触发;( Recompisition not taken effect in innerList
