DataTables 自适应问题

怎么让表格DataTables中的列自适应不超过外面那个宽度

$('#LinuxDataTable').DataTable( {
"destroy": true,
scrollY: 300,
scrollX: true,
scrollCollapse: true,
bPaginate: true,
"aLengthMenu": [[-1, 200, 100,50], ["ALL", 200, 100,50]],
bLengthChange: true,
"bAutoWidth": true,
"aaSorting": [],
"oLanguage": {
"sProcessing": "正在加载中......",
"sZeroRecords": "对不起，查询不到相关数据！",
"sEmptyTable": "表中无数据存在！",
"sInfo":"显示第_START_ 至_END_ 项结果,共_TOTAL_ 项",
"sInfoFiltered":"从_MAX_条记录中搜索",
"sSearch": "搜索",
"oPaginate": {
"sFirst": "首页",
"sLast": "尾页",
"sNext": "下一页",
"sPrevious": "上一页"
}
}
} );
