Not able to excecute the code

I am trying to execute following codes :

 rows={'A','B'};
 data = cell(0,5);
T = cell2table(data);
T.Properties.RowNames = rows; 

Matlab is throwing an error :The RowNames property must contain one name for each row in the table.

Can anybody comment if I am missing anything? I will appreciate any help.

Hey, cell(0,5) returns a 0x5 empty cell array. That is why row number isn't matching with rows variable. You should use You can simply create a cell array using the command,

data = {0,5}

Also, in this example data is a 1x2 cell array. Hence it has only one row. To change that row name, you could do something like,

rows={'A'};
data = {0,5};
T = cell2table(data);
T.Properties.RowNames = rows; 

For creating a 2x1 cell array, you'll have to use

rows={'A','B'};
data = {0;5};
T = cell2table(data);
T.Properties.RowNames = rows;

Thanks very much for correcting the code. However I have stuck in one implementation where I want to create a table with just column and row name. I am trying in the following way

Step1 : tab1 = cell2table(...) ; tab2=cell2table(...) ;tab3=cell2table(...)

Step2 : table = [tab1 tab2 tab3]

step3 : table..Properties.RowNames = x_name ; x_name is a cell array of specied element (say it is of size 1x20)

This is throwing the following error : The RowNames property must contain one name for each row in the table. Can I create a table with only rows and column name?

[Walter Roberson]

No. You must have at least one column of value along with the row name, and that column must have as many rows as you have row names.

[Walter Roberson]

Further testing shows that to be incorrect: You can have rownames even with now columns.

What is showing up as size(table) ?

[Rajeev Kumar]

Thanks Walte size. Here is the result:

size(table)=0x3

h=table.Properties.VariableNames

h =

1×3 cell array

{'tab1'} {'t'ab2} {'tab3'}

Could you please comment on this?

[Walter Roberson]

With 0 rows you must have 0 row names.

First change the number of rows from 0 to 1 and correspondingly the rows array should contain only 1 element either 'A' or 'B'. Run it , it will work fine

Here is the code

rows={'A'};
 data = cell(1,5);
T = cell2table(data);
T.Properties.RowNames = rows; 

[Walter Roberson]

Right. You can only have a row name for a row that exists. You cannot put in placeholder row names for rows to be added later.
