How can I send data of the type "string" and "numeric" to a uitable?

Good afternoon. I annoy them again with a new concern. I'm making a GUI that has 2 tables:

1) The first call "TablaDatosElementos", which consists of 7 fixed columns and "n" rows, of the numerical values that are put in columns 6 and 7 is obtained the variable called "N_I_F" (a variable that tells me the numerical data of a vector without repeating them) and a variable "N_I_F_R" that records what these numerical data were.

2) The other table is called "Table_Rest" and has 2 fixed columns and "N_I_F" rows. I send this table the data of the vector "N_I_F_R" in its second column. The table "Table_Rest" in its first column has a "Choice list" of 4 options (in the form of a string) for each cell of said column (that is, the number of cells depends on the variable "N_I_F")

The doubt is the next one. After sending the data from "N_I_F_R" to "Table_Rest" and selecting some of the 4 Table options (in its first column) it shows me "NaN" instead of the option I selected, and I think that this problem is because the table is being worked as double, so I require that the data in the first column (column where the 4 options are) is handled as a string and the second is handled as a numeric data.

Thank you very much and I would appreciate your help. Here is my code.

    % --- Creacion de filas de la tabla "restricciones" de acuerdo al conteo de nodos
   N_I_F_R=unique(B1); 
   num_elem_Rest=cell(N_I_F,2);
   num_elem_Rest(:,:)={''};
   set(handles.Table_Rest,'data',num_elem_Rest);  

%------------------ LLenado de tabla de Nodos --------------- 
i=1;  
T_rest=get(handles.Table_Rest,'Data'); 
T_rest=[,];
for i=1:N_I_F  
 T_rest(i,2)=N_I_F_R(i,1);   
end 
set(handles.Table_Rest,'data',T_rest);

What code are you using to extract the cells in the table that the user highlighted? I believe the 'data' property just returns the whole table, regardless of what is selected by the user.

Thank you very much. And I want to make a correction, the first Table is called "TableDataElements" and not "NumElem" as I had originally put it.

 datos=get(handles.TablaDatosElementos,'Data');
 datos=str2double(datos);
-------------------------------------------
 N_I_F= N_I_F';
   Nodos1=[datos(1:VarElem_F,6),Ele_asc];
   Nodos2=[datos(1:VarElem_F,7),Ele_asc];
   NodosT=[datos(1:VarElem_F,6:7),Ele_asc];
   ZZZ=[Nodos1;Nodos2]; 
   B1=[ZZZ,N_I_F]; 
   B1=sortrows(B1,1); 
   N_I_F=length(unique(B1));

Uh, okay . . . but are you still going to answer my question?

[Pedro Guevara]

That is the code that you asked me, or at least that's what I understood.

You said "selecting some of the 4 Table options (in its first column)". Does that not mean that you, as the user, are selecting only SOME of the items in column 1, and you want (in your code) to find out which cells were selected?

[Pedro Guevara]

I want that for each cell created in the table "Table_Rest" one of the 4 options can be given and that when selecting the option for each cell, the selected option appears in that same cell and not the "NaN" error that currently appears. I leave you an image so that you understand better what happens

1) Here you can see that for each cell created there are my 4 options

2) but after selecting any of them I get "NaN"
