Answer 1

headerRowHeight 为 0，空容器为 DataColumn 标签

DataTable(
         headingRowHeight: 0,
         columns: [
           DataColumn(label: Container()),
           DataColumn(label: Container()),
           DataColumn(label: Container()),
           DataColumn(label: Container()),
           DataColumn(label: Container()),
         ],
         rows: ..
    ),

Answer 2

将 headerRowHeight 设置为 0 并将所有标签文本设置为空字符串DataColumn(label: Text(""))。
