[SOLVED] Is there a way to create a table with multi-line column names?

Is there a way to create a table with multi-line column names?

I am attempting to create a table that has the following format of multi line heading for the columns

|Col1 Co2 Col3|

|Col1 Co2 Col3|

Tried this using the example and adding a | between 1st and 2nd line but did not work

T = table(categorical({'M';'F';'M'}),[45;32;34],...

      {'NY';'CA';'MA'},logical([1;0;0]),..

      'VariableNames',{'Gender|Gender2','Age|Age2','State|State2','Vote|Vote2'})

I am using R2018b student edition

Solution

The ability to have arbitrary variable names in tables was added to release R2019b of MATLAB. Using that release, your code works as expected and produces:

T =
  3×4 table
    Gender|Gender2    Age|Age2    State|State2    Vote|Vote2
    ______________    ________    ____________    __________
          M              45          {'NY'}         true    
          F              32          {'CA'}         false   
          M              34          {'MA'}         false

However, in your question you state that you want multi-line variables. You can make these in R2019b, but the display collapses the newline character into a ↵, like this:

>> T = table(1, 'VariableNames', {['a', newline, 'b']})
T =
  table
    a↵b
    ___
     1

If it's just the display you're after, you could consider making nested tables, like this:

t1 = table(1);
t2 = table(2);
T = table(t1, t2)

which results in:

T =
  1×2 table
     t1      t2 
    Var1    Var1
    ____    ____
     1       2

Note that that final approach works in R2019a and prior releases.
