Hi Abdullah,

The challenge you are facing arises when the new results are added to the table without preserving the existing data, resulting in the current content being overwritten. To address this, kindly ensure that you retrieve the current data from the table before incorporating any new entries.

For guidance on updating the table while maintaining the existing data, please refer to the documentation and code provided below.

Create table user interface component - MATLAB uitable (mathworks.com)

% txt1 is the textfield1, txt2 is textfiled2 and tb1 is table
function onButtonPushed(txt1, txt2, tbl)
    % Get the numbers from text boxes
    num1 = txt1.Value;
    num2 = txt2.Value;
    
    % Combine the numbers as a string
    combinedStr = sprintf('%d%d', num1, num2);
    
    % Get the current row index from UserData
    currentRow = tbl.UserData;
    
    % Get current data from the table
    currentData = tbl.Data;
    
    % Ensure the table has enough rows
    if size(currentData, 1) < currentRow
        currentData{currentRow, 1} = combinedStr;
    else
        currentData{end+1, 1} = combinedStr;
    end
    
    % Update the table data
    tbl.Data = currentData;
    
    % Increment the row index for the next entry
    tbl.UserData = currentRow + 1;
end
