Hey All,

I am new to Matlab and have a table with a subtable in some cells. My main Table (MM) has dynamic size and the subtable, which is in the 9th cell of each row has to have a subtable with the width of the hight of the Maintable. I have trouble if i add a row to add a column to the subtable. My Idea is:

for i = 1:size(MM,1)
    MM{i,9} = table([MM{1,9}{1,1} 1]);
end

Following error message comes up: "Subscripted assignment dimension mismatch for table variable 'Var1'."

I also tried the following:

for i = 1:size(MM,1)
    MM{i,9}{1,1} = [MM{1,9}{1,1} 1];
end

Following error message comes up: "The value on the right-hand side of the assignment has the wrong width. The assignment requires a value whose width is 3."

It seems like I cant change the size of the subtable but dont get why. Please help me.

Thank you!

Arne

Attach a .mat file with a small example of the table structure and illustrate what you want the result to be...

table.mat

I added the table.mat file. The Variable MM is the table. For adding a row I have following code

function addSolution(pos, solution)
%%fügt der Tabelle tabelle eine technische Lösung hinzu
tabelle = getMM(pos);
rows = height(tabelle);      
columns = width(tabelle); 
T = table();
for i = 1:8
    T = [T table(0)];
    T.Properties.VariableNames{i} = tabelle.Properties.VariableNames{i};
end
T = [T {table(ones(1,rows))}];
T.Properties.VariableNames{9} = tabelle.Properties.VariableNames{9};
for i = 10:columns
    T = [T table(addCell)];
    T.Properties.VariableNames{i} = tabelle.Properties.VariableNames{i};
end
T.Properties.RowNames = {solution};
if rows == 0
    tabelle = T;
else
    tabelle = [tabelle;T];   
end
setMM(pos,tabelle);
for i = 1 : rows+1
    modules = [table2array(getMM([pos;i,9])) 1];
    setMM([pos;i,9],{modules});
end

The pos variable is in first step emtpy [].

The last four Rows in this code should add a column to the Matrix in the 9th cell. This still dont work.

Hi Arne,

My understanding is that you are looking into changing the dimensions of your sub-tables. In MATLAB you would be able to add nested/sub tables inside your main table of desirable width/variables but the number of rows of each sub-table should be equal to the number of rows of the main table.

For reference please do look into this answer.
