How can I display a table with many rows?

Hi everyone, i have a problem: i want to create a table with 42 rows and 19 column, i used these commands

T = table(I_S_A,I_O_P, I_M_A, I_S_E, I_R_P, I_G,I_E_I, I_E, I_E_N, I_L_P, I_H_R, I_S, I_P, I_E_F,...
   I_S_D_G, I_P_G, I_T_G, I_4_0, I_C_E);
T(1:42,:)

But the answere in Command Window is :

"Error using prova (line 1099)

Row index exceeds table dimensions. "

How can i fix it? .Inserting T (1:41,:) the table comes out but with T(1:42,:) no. Who helps me? thank you very much in advance!

Apparently, the vectors that create the table only have 41 elements. In a table, the first row (the 'VariableNames') is not considered part of the table data, and so cannot be addressed as part of the data.

Thanks for replying, ok sorry so I need 43 lines but Matlab gives me an error

My pleasure.

My original Answer still applies.

I would need to see the vectors that created the table (They should all be column vectors) to more accurately determine what the problem is.

I am lost.

‘Can you help me?’

Probably not, on the basis of the information provided.

This will preallocate a 3-element row vector:

I_S_A=zeros(1,3);

and depending on what ‘k’ is, this:

I_S_A(k)=mean(categoria_S_A);

will create another row vector. That will likely not be compatible with the sort of table you want, since it is necessary to use column vectors to create the sort of table you appear to want to use.

I have no idea what you are doing.

Use the readtable function instead of creating your own table from whatever it is that you are doing.

See the section on Text and Spreadhseet Files for information on how to read the variable names and row names.

okok thanks!
