A shortcut for recurring if statements

Hello, I have a case where I don't know how many elements a vector will have and then depending on different size vectors I'll either include something or not include something.
For example, what I have now is just
if numtable2rows >=2
tablerow(2,:) = tablerow(1,:) + [0 50 0 0];
end
if numtable2rows >=3
tablerow(3,:) = tablerow(2,:) + [0 50 0 0];
end
if numtable2rows >=4
tablerow(4,:) = tablerow(3,:) + [0 50 0 0];
end
if numtable2rows >=5
tablerow(5,:) = tablerow(4,:) + [0 50 0 0];
end
and I'm just expecting no more than 5 elements in numtable2row.
Does anyone know a more efficient way to do this?
Thank you in advance!

@tiwwexx: that algorithm seems unusual, because it discards the existing row data. Is that correct? In any case, please provide some example data, with both input and output matrices.

You fixed the size() but not the fact that tablerow(k) is a scalar.
tablerow(1,:) = [a b c d];
for k= 1:numtable2rows
tablerow(k+1,:) = tablerow(k, :) + [0 50 0 0];
end

for K = size(tablerow,2)+1 : 5
tablerow(K,:) = tablerow(K-1,:) + [0 50 0 0];
end
