title: How to change background color of DataColumn in Flutter?
body: <p>I have a <code>DataTable</code> widget for displaying some data in tabular format. I wasn't able to find any way to change the background color of the <code>DataColumn</code>, it defaults to white.</p>
  
  <p>I tried wrapping the <code>label</code> inside a <code>Container</code> but that does not help since the container takes the dimensions of the child.</p>
  
  <p>Is there any easier way to set the background color of `DataColum'?</p>
  
  <p>Below is some code for reference -</p>
  
  <pre><code>DataTable(
    dataRowHeight: 70,
    headingRowHeight: 60,
    rows: List.generate(4, (index) {
      return DataRow(
        cells: &lt;DataCell&gt;[
          DataCell(
            Text("Number",),
          ),
          DataCell(
            Text(
            "Lorem ipsum dolor sit amet, consectetur adipiscing elit.",
            ),
          ),
        ]
      );
    }),
    columns: [
      DataColumn(
        label: Text("Name"),
      ),
      DataColumn(
        label: Text("Description"),
      ),
    ],
  )
  </code></pre>
