Widget DataTable 有一个内置图标用于排序指示

如何更改颜色甚至图标？

                Scrollbar(
                  controller: _scrollController,
                  child: SingleChildScrollView(
                    controller: _scrollController,
                    scrollDirection: Axis.horizontal,
                      child: DataTable(
                      border: TableBorder.all(width: 0.2),
                      headingRowColor: MaterialStateProperty.resolveWith<Color?>(
                          (Set<MaterialState> states) {
                        return Styles.TableHeaderColor;
                      }),
                      columns: getColumns(TableTitles),
                      rows: getRows(),
                      sortColumnIndex: sortColumnIndex,
                      sortAscending: isAscending,
                      dataRowHeight: 50,
                      headingRowHeight: 40,
                    ),
                  ),
                ),
