表格宽度大于内容，如何让内容填充表格？
样式目前是这样写的

 table.table { 
    margin-left: auto; 
    margin-right: auto;
    border: 1px solid black; 
    line-height: 1.25;
    width: 90%;
    text-align: center; 
    border-spacing: 0px 1px; 
    border-collapse: collapse;
    table-layout:fixed;
}

table.table th { 
    border: 1px solid black;
    line-height: 1;
    padding: 7px;
    background-color: #dddddd;
    text-align:center;
}

table.table td { 
    border: 1px solid black; 
    padding: 5px;
}
