An another alternative:
ix = (5:7:size(TABLE,1)) + [0;1;2];
%if > 2016b ix = bsxfun(@plus, 5:7:size(TABLE,1), [0;1;2])
TABLE(ix(ix<=size(TABLE,1)),:) = []
%or if you want to delete only in chunks of three then
TABLE(ix(:,all(ix<=size(TABLE,1))),:) = []

If your vector is a multiple of 7 in length, then this will work:
x = reshape(x,7,[]);
x = x(1:4,:);
x = x(:);
