如何在 Anko 的 gridLayout 中设置元素的列值和行值？

我试了几个版本，但是这个编译不了：

   return UI {
        gridLayout() {
            columnCount = 2
            rowCount = 3
            button("1x1") {

            }.lparams() { column = 1; row = 1 }
        }
    }.view

当我像这样（作为函数）或作为大括号内的属性时，它说它不能引用 column 或 row。当我将它们作为 lparams 的参数提供时，它说 none of the following functions can be called with arguments supplied.

如 GridLayout 文档中所述：

Children occupy one or more contiguous cells, as defined by their rowSpec and columnSpec layout parameters. Each spec defines the set of rows or columns that are to be occupied; and how children should be aligned within the resulting group of cells.

您可以像这样使用 rowSpec 和 columnSpec：

return UI {
    gridLayout() {
        columnCount = 2
        rowCount = 3
        button("1x1") {

        }.lparams {
            rowSpec = GridLayout.spec(1)
            columnSpec = GridLayout.spec(1)
        }
    }
}.view
