flutter DataTable multiline wrapping and centering - flutter

Question

I'm trying to have multiple, centered lines in the DataColumn() row of a DataTable() in flutter. It seems, though, that there is no support for centering or for multiple lines.
My DataTable Code looks something like this:
class TestDayData extends StatelessWidget {
final List<String> timesList = [
"This is",
"a bunch",
"of strings",
];
final String day;
TestDayData({Key key, this.day}) : super(key: key);
#override
Widget build(BuildContext context) {
return Container(
child: DataTable(
showCheckboxColumn: false,
columns: [
DataColumn(
label: Center(child: Text(day)),
numeric: false,
),
],
rows: timesList
.map(
(times) => DataRow(cells: [
DataCell(
Text(times.toString()),
),
]),
)
.toList(),
),
);
}
}
I made a dartpad file here to show the above code in a larger context. (the reason that I am putting multiple DataTables in a Row widget, instead of using one DataTable for all of the days, is because I plan on putting each of them into a Stack widget so that I can overlay appointments on top of the columns.)

So far, I can approximate a multi-lined, centered DataColumn row by adding spaces and using a newline character as seen in the dartpad file. (but there has to be a better way!)

Answer 1

You are missing textAlign property in Text widget
DataTable(
showCheckboxColumn: false,
columns: [
DataColumn(
label: Center(child: Text(day, textAlign:TextAlign.center)),
numeric: false,
),
],
rows: timesList
.map((times) => DataRow(cells: [
DataCell(
Text(times.toString(), textAlign: TextAlign.center),
),
]),
)
.toList(),
),

Answer 2

You can try this to center your text in Datacolumn
DataColumn(
label: Center( widthFactor: 1.4,
child: Text("HELLO", textAlign: TextAlign.center,
style: TextStyle(fontSize: 18.0,),),)),
You can try this to center your text in Datacell for rows.
DataCell( Center(child: Text("Hello")))

Answer 3

For me on the DataColumn, using the Center widget or the textAlign property on the Text widget didn't work:
this is my solution:
DataColumn(
label: Expanded(
child: Row(
mainAxisAlignment: MainAxisAlignment.center,
children: const [Text("text")],
),
),
),
DataCell worked just fine with the Center widget

Answer 4

I figured out the solution.
you just need to wrap the text with Center widget and then wrap it again with Expanded widget just like this:
DataTable(
columns: [
DataColumn(label: Expanded(child: Center(child: Text('ID', textAlign: TextAlign.center,))),),
DataColumn(label: Expanded(child: Center(child: Text('name', textAlign: TextAlign.center,)))),
]
)
