SliverTable class

A sliver that displays a two dimensional scrollable (in both directions) grid of box children. The table consists of a horizontal top header, a vertical left header, and a rowsCount x colsCount grid of cells. The vertical header is pinned at the top edge of the table and displays colsCount cells that are horizontally scrollable. The horizontal header is pinned at the left side of the table and displays rowsCount cells that are vertically scrollable. The grid of cells can scroll both vertically and horizontally under the top and left headers respectively.

The topHeaderBuilder builder callback is used to build the top header's cells, where each cell will be given a height of topHeaderHeight and a width of cellWidth.

To wrap the whole top header in another widget, you can use the topHeaderContainerBuilder callback, which can be used, for example, to add a background color.

The leftHeaderBuilder builder callback is used to build the left header's cells, where each cell will be given a height of cellHeight and a width of leftHeaderCellWidth.

The cellBuilder builder callback is used build the grid's cells, where each cell will be given a height of cellHeight and a width of cellWidth.

The topLeftCorner is used to add any type of widget to the top left corner of the table.
