    width:100px;
    float:left;
}
.use-float>div:last-child{
    overflow:hidden;

.use-table{
    border-collapse:collapse;
    width:100%;

    display:table;
    width:100%;

}
.use-mock-table>div:first-child{
    width:100px;
}

.use-flex{
    display:flex;
}
.use-flex>div:first-child{
    flex:none;
    width:100px;
}
.use-flex>div:last-child{
