ie11浏览器 css:怎么让a标签里的img居中

1、我最患束锍瓜开始的样式是这样的：a{ display:block; width: 365px; height:100px; text-align: center; line-height: 100px; background: url(../images/bank_bj02.png) no-repeat;}a img{ display:inline-table; vertical-align: middle;}ie11显示是这样，而在其他浏览器都能正常居中显示

2、后来改成：a{display:table-cell;vertical-align:middle;width: 365px;height:100px; text-align: center; line-height: 100px;background: url(../images/bank_bj02.png) no-repeat;}a img{ display:inline; vertical-align: middle;}正常显示了
