I would like to convert a table from Mircosoft Excel to latex (on Winedt) based on Microsoft Windows operation system. The number in excel is, for instance,

---

1 2 

1.00E-02 1.05E-03

---

I would like to have 1.00 $\times 10^{-2}$ and 1.05$\times 10^{-3}$ in latex table directly. 

I have tried excel2latex.xla, it could convert table, but does not change formatting as $\times 10^{-2}$. Is there any simple way to do that? though I am somehow doubt about it...
