That does what I am looking for.  Thank you for the quick reply!

try to take slice from static arrays
writeln(ta[1][].maxElement);
or use dynamic arrays (slices)
int[][] ta = [[2, 1, 4, 3], [3, 10, 2, 5]]; // or auto ta

Finding the maxElement of Two-Dimensional Array

[Samir via Digitalmars-d-learn]

How come this works:

int[][] ta = [[2, 1, 4, 3], [3, 10, 2, 5]];
writeln(ta[1].maxElement); // 10

but I get an error when specifying the number of elements when 
declaring the array:


int[4][2] ta = [[2, 1, 4, 3], [3, 10, 2, 5]];
writeln(ta[1].maxElement); // get error on this line

Error: template std.algorithm.searching.maxElement cannot deduce 
function from argument types !()(int[4]), candidates are:

/home/samir/dlang/dmd-2.082.0/freebsd/bin64/../../src/phobos/std/algorithm/searching.d(3576):
std.algorithm.searching.maxElement(alias map = (a) => a, Range)(Range r) if 
(isInputRange!Range && !isInfinite!Range)
