Add cell to table

Hi there, novice user so please forgive any errors. Using Matlab R2022a. I have a large table (7x1516) and a cell (1x1516) with what I want to be the variable names for the table. It is obviously too big to just do normal VariableNames, is there a way to just merge these two to make the contents of the cell be the header of the table? Thanks!

As a simplified example,

T=array2table(rand(4,5)); %A randomly generated table

T = 4×5 table
     Var1       Var2       Var3       Var4        Var5  
    _______    _______    _______    _______    ________

    0.74225    0.40712    0.24696    0.29999    0.087221
    0.65439    0.73105    0.69865     0.1184    0.023813
    0.84447    0.36567    0.97351    0.77847     0.44329
    0.42092    0.66762    0.91108    0.32112     0.81036

Headings={'dog','cat','fish','fox','hamster'}; %desired column headings

T.Properties.VariableNames=Headings  %add the headings

T = 4×5 table
      dog        cat       fish        fox      hamster 
    _______    _______    _______    _______    ________

    0.74225    0.40712    0.24696    0.29999    0.087221
    0.65439    0.73105    0.69865     0.1184    0.023813
    0.84447    0.36567    0.97351    0.77847     0.44329

That worked to rename my variables in the table, but now every cell is displaying '1x1 table'? When I open the cell in its own tab it still has the values, but is there any way to actually view the data in the table? Thanks!

[Matt J]

I suggest attaching the original table in a .mat file, and also the cell vector with the desired headings.

[MARTINA ROGERS]

This is currently within a script that I need to be streamlined, so I would like to avoid that if possible. I don't really care so much if it is displaying the 1x1 table text instead of actual values, but I think it is interfereing with plotting the data. When I try to plot it ( plot(table.variablename) ) I get the error "When table is the second input, the first input must be a valid parent.". Is this an easy mistake I'm getting wrong, or is it because of the 1x1 table display?

[MARTINA ROGERS]

Nevermind, I figured it out thanks!

how'd you figure this out, I'm getting the error "When table is the second input, the first input must be a valid parent"
