Find and extract specific rows and column into new table

This is what I have and it finds the correct rows but it is not creating a new table with the extracted values. It produces a 1x1 table. I am not sure what I am missing.

load Leaf1.txt;

% % Set data source

Wave = Leaf1(:,2);
Ref = Leaf1(:,3);

% % Locate data
R = find(Wave >= 625 & Wave <= 691)
NIR = find(Wave >= 829 & Wave <= 900);

% Create new matrix
New = Leaf1([276:342 2427:2493 4578:4644 6729:6795 8880:8946 11031:11097 13182:13248 15333:15399 17484:17550 19635:19701 480:551 2631:2702 4782:4853 6933:7004 9084:9155 11235:11306 13386:13457 15537:15608 17688:17759 19839:19910]);

% % Save new table
Ref_Leaf1=table(New);
writetable(Ref_Leaf1);

New = Leaf1([276:342 2427:2493 4578:4644 6729:6795 8880:8946 11031:11097 13182:13248 15333:15399 17484:17550 19635:19701 480:551 2631:2702 4782:4853 6933:7004 9084:9155 11235:11306 13386:13457 15537:15608 17688:17759 19839:19910], :);
Ref_Leaf1 = array2table(New, 'VariableNames', {'Wave', 'Ref'});

But I suspect you are more after

Leaf_R = array2table( Leaf1(R, :), 'VariableNames', {'Wave', 'Ref'});
Leaf_NIR = array2table( Leaf1(NIR, :), 'VariableNames', {'Wave', 'Ref'});

writetable(Leaf_R);
writetable(Leaf_NIR);
