If by 'table', you mean an array:
result = myArray( 2:4, 2:4 );
will read, for example, the 2nd to 4th rows and 2nd to 4th columns, giving you a 9-by-9 result array.
If you mean an actual 'table' structure then I am less familiar with that, but
doc table
seems to give various examples of manipulating table data.

result = myArray( [1 end], : );
result = myArray( :, [1 end] );
will give you, respectively, the 1st and last row and the first and last column (assuming you want all columns for each row and all rows for each column)
