MATLAB: Aligning columns with fprintf

fprintfMATLAB

All of my data is correct, however I cannot figure out how to format the top numbers correctly. The only problem I am having is I do not know how to align the numbers correctly without adding a decimal value. I would like to know how to align the whole numbers, like 1.0 and 2.0, without the 0 in the decimal place. I know %2.1f adds a number behind the decimal automatically, but could someone show me how I could align them without a deciamal behind whole numbers? Below is my code and a picture of my output. Keep in mind this is in a for loop.
fprintf('%2.1f    ',incWater(numCol+1))
This is what my code is supposed to look like:

You can use '%g' to print values with trailing zeros removed:
X = 0.5:0.5:2.5;
Y = 500:250:1500;
M = [425,1441,2651,3665,4091;638,2160,3976,5498,6136;851,2880,5301,7330,8181;1064,3600,6627,9163,10227;1276,4320,7952,10996,12272];
N = numel(X);
F = repmat('%8.2g',1,N);
fprintf(sprintf('        %s\n',F),X)
F = repmat('%8.0f',1,1+numel(X));
fprintf(sprintf('%s\n',F),[Y;M.'])
Prints:
             0.5       1     1.5       2     2.5
     500     425    1441    2651    3665    4091
     750     638    2160    3976    5498    6136
    1000     851    2880    5301    7330    8181
    1250    1064    3600    6627    9163   10227
    1500    1276    4320    7952   10996   12272
