This is a multi axis scrollable data table, that allows you to scroll on both the vertical and horizontal axis, with the header remaining static on the vertical axis. Please look at the demo below.

This widget serves the same purpose as a DataTable, with the advantage that it can scroll in both the horizontal and vertical axis, while maintaining the vertical position of the header.

Simply add into your dependencies the following line.

dependencies:
  scrollable_table_view: <latest-version>

ScrollableTableView(
  columns: [
    "product_id",
    "product_name",
    "price",
  ].map((column) {
    return TableViewColumn(
      label: column,
    );
  }).toList(),
  rows: [
    ["PR1000", "Milk", "20.00"],
    ["PR1001", "Soap", "10.00"],
  ].map((record) {
    return TableViewRow(
      height: 60,
      cells: record.map((value) {
        return TableViewCell(
          child: Text(value),
        );
      }).toList(),
    );
  }).toList(),
);

Pagination is supported from version 1.0.0-beta. First, initialize a PaginationController as follows:

final PaginationController paginationController = PaginationController(
    rowCount: many_products.length,
    rowsPerPage: 10,
  );

Next, initialize your table and pass the pagination controller to the paginationController parameter:

ScrollableTableView(
  paginationController: paginationController,
  columns: columns.map((column) {
    return TableViewColumn(
      label: column,
    );
  }).toList(),
  rows: many_products.map((product) {
    return TableViewRow(
      height: 60,
      cells: columns.map((column) {
        return TableViewCell(
          child: Text(product[column] ?? ""),
        );
      }).toList(),
    );
  }).toList(),
)

With the above setup, navigate forward and backwards using paginationController.next() and paginationController.backwards() respectively. To jump to a page directly, use paginationController.jumpTo(pageToJumpTo).

For the full example, go to the main.dart file in the example project.
