How Compare two sheet in open office and mark different value with color

Question

In first sheet original data and in second modify data so i want to compare both sheet data and mark with color if sheet1 and sheet2 data not match.

I have two different sheet with data as per below.

Sheet1:

--------A-----B-----C
1-------T10---T10---T40
2-------T34---T65---T20

Sheet2:

--------A-----B-----C
1-------Z10---T10---T40
2-------T34---T65---T20

ABC is represent the columns. 1-2 is represent row.

I can write the conditional format on single cell to check if Sheet1.A1 <> Sheet2.A1 and change the background colour.

conditional formatting : "Cell Value is" "equal to" $Sheet1.A$1 Cell Style "BACK_COLOR_RED".

But the problem is that how can i apply this same conditional format on sheet all cell to compare both sheet as manually write the same formula on one by one cell is not feasible.
