row: RowThemeData(dividerThickness: 4, dividerColor: Colors.green),
scrollbar:
TableScrollbarThemeData(columnDividerColor: Colors.orange)));
Header #
EasyTableTheme(
child: EasyTable<Person>(_model),
data: EasyTableThemeData(
header: HeaderThemeData(
color: Colors.green[50],
bottomBorderHeight: 4,
bottomBorderColor: Colors.blue),
headerCell: HeaderCellThemeData(

resizeAreaHoverColor: Colors.blue.withOpacity(.5),
sortIconColor: Colors.green,
expandableName: false)));
Hidden header
EasyTableTheme(
child: EasyTable<Person>(_model),
data:
const EasyTableThemeData(header: HeaderThemeData(visible: false)));
Row #
Theme Row color
EasyTableTheme(
data: EasyTableThemeData(
row: RowThemeData(color: (rowIndex) => Colors.green[50])),
child: EasyTable<Person>(_model));
Row zebra color
EasyTableTheme(
data: EasyTableThemeData(
row: RowThemeData(color: RowThemeData.zebraColor())),
child: EasyTable<Person>(_model));
Row hover background
EasyTableTheme(
data: EasyTableThemeData(
row: RowThemeData(hoverBackground: (rowIndex) => Colors.blue[50])),
child: EasyTable<Person>(_model));
Row hover foreground
EasyTableTheme(

Scrollbar #
EasyTableTheme(
child: EasyTable<Person>(_model),
data: const EasyTableThemeData(
scrollbar: TableScrollbarThemeData(
thickness: 16,
thumbColor: Colors.black,
pinnedHorizontalColor: Colors.yellow,
unpinnedHorizontalColor: Colors.green,
verticalColor: Colors.blue,
borderThickness: 8,
pinnedHorizontalBorderColor: Colors.orange,
unpinnedHorizontalBorderColor: Colors.purple,
verticalBorderColor: Colors.pink)));
Scrollbar always visible
EasyTableTheme(
data: const EasyTableThemeData(
scrollbar: TableScrollbarThemeData(
horizontalOnlyWhenNeeded: false,
verticalOnlyWhenNeeded: false)),
child: EasyTable<Person>(_model));
A warning is being displayed in the console due to a bug in Flutter: https://github.com/flutter/flutter/issues/103939. The error happens when the horizontal scrollbar is hidden after being visible. The PR (https://github.com/flutter/flutter/pull/103948) fix it.
