title: Flutter DataTable remove extra padding
body: <p>I want to display some data in a <code>DataTable</code>, i have 9 columns, all of them are number except the first one.</p>
  
  <p>The problem i'm having is, i only see the first 5 columns, not because data are too long, but because there are a lot of space between every column.</p>
  
  <p><a href="https://i.stack.imgur.com/ANkHb.png" rel="noreferrer"><img src="https://i.stack.imgur.com/ANkHb.png" alt="enter image description here"></a></p>
  
  <p>Is there a way to make the DataColumn wrap the data with a padding i choose?
  This is my code:</p>
  
  <pre><code>Scaffold(
    appBar: AppBar(
      title: Text('DataTable Sample'),
    ),
    body: Container(
      child: DataTable(columns: &lt;DataColumn&gt;[
            DataColumn(
              label: Text('Name'),
            ),
            DataColumn(
              label: Text('A'),
            ),
            DataColumn(
              label: Text('B'),
            ),
            DataColumn(
              label: Text('C'),
            ),
            DataColumn(
              label: Text('D'),
            ),
            DataColumn(
              label: Text('E'),
            ),
            DataColumn(
              label: Text('F'),
            ),
            DataColumn(
              label: Text('G'),
            ),
            DataColumn(
              label: Text('H'),
            ),
          ], rows: &lt;DataRow&gt;[
            DataRow(cells: [
              DataCell(Text('1 Boston')),
              DataCell(Text('3')),
              DataCell(Text('3')),
              DataCell(Text('7')),
              DataCell(Text('1')),
              DataCell(Text('30')),
              DataCell(Text('8')),
              DataCell(Text('+2')),
              DataCell(Text('-22')),
            ]),
            DataRow(cells: [
              DataCell(Text('2 London')),
              DataCell(Text('3')),
              DataCell(Text('4')),
              DataCell(Text('12')),
              DataCell(Text('44')),
              DataCell(Text('7')),
              DataCell(Text('44')),
              DataCell(Text('-98')),
              DataCell(Text('0')),
            ]),
            DataRow(cells: [
              DataCell(Text('3 Rome')),
              DataCell(Text('10')),

              DataCell(Text('4')),
              DataCell(Text('7')),
              DataCell(Text('33')),
              DataCell(Text('+5')),
              DataCell(Text('-61')),
            ]),
          ]
          )
    ),
  );
  </code></pre>
