Bug description

When printing a table with a column containing an enumeration array, the padding is messed up.

What should have happened?

>> disp(T)
        Var1             Var2     
    _____________    _____________

    A                A            
    VeryLongEntry    VeryLongEntry
    Test             Test         

>> 

What did actually happened?

>> disp(T)
        Var1             Var2     
    _____________    _____________

    A    A
    VeryLongEntry    VeryLongEntry
    Test    Test

>> 

Steps to reproduce the bug

1. Define an enumeration class with variable lengths:

   classdef TestEnum
   enumeration
       A
       VeryLongEntry
       Test
   end
   end

2. Create an array C with instances of that class:

   C = arrayfun(@(S) S,enumeration('DataKit.Metadata.TestEnum'));

3. Create a table T containing that array as columns:

   T = array2table([C,C]);

4. Then print the table to the command window with disp(T)

Causes & solutions

The file MATLAB_R2017b.app/toolbox/matlab/datatypes/@tabular/disp.m has a faulty line for enumaration data types. Replace line 177

maxVarLen = max(strlength(varStr));

with

[varStr, maxVarLen, lostWidth] = alignTabularContents(varStr, lostWidth);
