Apologies in advance for the lengthy example below. Suppose I create a two-column table:
>> t=table((1:2)',repmat(1:5,2,1))
t =
2×2 table
Var1 Var2
____ _____________________
1 1 2 3 4 5
2 1 2 3 4 5
At some point, MATLAB renders the second column in a "compact" format. In this case, this is triggered by adding a sixth element to the arrays in the second column:
>> t=table((1:2)',repmat(1:6,2,1))
t =
2×2 table
Var1 Var2
____ ____________
1 [1×6 double]
2 [1×6 double]
The same thing happens with chars, for which the magic threshold seems to be 10 characters; beyond that, the "compact" format appears:
>> t=table((1:2)',repmat('abcdefghij',2,1))
t =
2×2 table
Var1 Var2
____ __________
1 abcdefghij
2 abcdefghij
>> t=table((1:2)',repmat('abcdefghijk',2,1))
t =
2×2 table
Var1 Var2
____ ___________
1 [1×11 char]
2 [1×11 char]
I'm trying to understand if there is a way to set the width threshold for when this happens. Things I've tried that DO NOT work:
- Setting the header of the second column to an artificially long name:
>> t=table((1:2)',repmat(1:6,2,1),'VariableNames',{'Short','AVeryLongVariableNameThankYouVeryMuch'})
- Using addprop:
>> t=addprop(t,'ColumnWidth','table');
>> t.Properties.CustomProperties.ColumnWidth=[30 100]
(and using 'variable' instead of 'table' produces the same output.)
- Setting output numerical output format:
>> format long e
(and similarly with all the other options I tried with that command.)

No, there is not. Those limits are hard-coded in near line 33 of @tabular/disp.m
table() objects are not designed as display objects.

Index in position 1 exceeds array bounds (must not exceed 1).

whos table
whos repmat
if one of them shows up as being a variable then clear the variable.

Walter, thank you for your timely response(s) by the way. Much appreciated. It's working now! I'm actually trying to accomplish two things.
- The "Select_Sensor" column is currently cut-off at the right.
- Ideally, I would like the option of three "Categorical" dropdown menus, one for each column.
As it is, only the first column on the left ("Crew1, Crew2,... etc.) has been expanded to include dropdowns. See the attached script.

Attached reply. I had already tried typing "clear" by the way.
