IE issue with css attribute position and z-index inside table

I've an IE issue,

There's a structure, where I want td has css attribute z-index:1, position:relative. It appears how it has to be appear in other browser than IE. Do I开发者_运维百科E(7,8) support this attribute in table ?

Sadly

The effect of 'position:relative' on table-row-group, table-header-group, table-footer-group, table-row, table-column-group, table-column, table-cell, and table-caption elements is undefined.

So you can't blame IE this time =p

Can't you apply these rules on a child of table-cell element?
