No 2D arrays in shell but you can create an array of arrays.
Does your file have 4 columns ?
To know the best way to store the data, we'll have to know what kind of process you want to applicate to the data.

example
Code:
NB=1
while read -a LINE # -a to put it in an array
do
	DATA[$NB]="${LINE[@]}"
	(( NB ++ ))
done

That puts every line in an array (LINE) and you put every LINE array in an array named DATA.

To get the data in [X,Y] :
Code:
LINE=${DATA[$Y]}
VALUE=${LINE[$X]}
