Convert this java array to a kotlin equivalent array 2d

Question

Hi I'm trying to convert this java array to a kotlin array:

String[][] data = {{"May","22"},
                        {"June","45"}};

I tried two ways but my tableView is not showing any record. This is my way number 1:

val mayo: Array<String> = arrayOf("Mayo", "20")
val junio: Array<String> = arrayOf("Junio", "40")
val data2d1 = arrayOf(mayo, junio)

The I pased this array to the adapter of this library: https://github.com/ISchwarz23/SortableTableView

  tableViewSalesPerMonth.dataAdapter = SimpleTableDataAdapter(requireContext(), data2d1)

and nothing happens, there is not data and not errors.

And this the way number 2 I created the next array by using the first array data2d1:

    val data2d2 = mutableListOf<Array<String>>()
    data2d2.addAll(data2d1)

This arrays that I did are wrong? I need something like:

  String[][] data = {{"May","22"},
                            {"June","45"}};

but in kotlin code. Please guys if you have any idea to fix this problem I will appreciate it. Thanks so much.

var values = arrayOf(arrayOf("may", "33"), arrayOf("jun","32")) may be ok but my table doesn't show anything. — FreddicMatters

The problem seem to be the libray is not showing any record. — FreddicMatters

Are you quite certain you didn't make any typos? There is no possible difference between your code and the Java code you have shown us. — Louis Wasserman

No errors bro. I will implement the default tableLayout of android instead of this library — FreddicMatters

I think what you are looking for is nested array, your second approach was correct.

val arr: Array<Array<String>> = arrayOf(
    arrayOf("May","222"),
    arrayOf("Hell","222")
)
