visualização de tabela rolável

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.

Features

Demo

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.

Note

For more complex features like freezing columns and rows, kindly take a look at the data_table_2 package

Getting started

Simply add into your dependencies the following line.

dependencies:
  scrollable_table_view: <latest-version>

Usage

ScrollableTableView(
  headers: [
    "product_id",
    "product_name",
    "price",
  ].map((label) {
    return TableViewHeader(
      label: label,
    );
  }).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

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,
  headers: labels.map((label) {
    return TableViewHeader(
      label: label,
    );
  }).toList(),
  rows: many_products.map((product) {
    return TableViewRow(
      height: 60,
      cells: labels.map((label) {
        return TableViewCell(
          child: Text(product[label] ?? ""),
        );
      }).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.
