amna - are you creating your GUI with GUIDE, App Designer, or programmatically? Please clarify.

If using GUIDE, then you could do something like the following (I'm assuming that you have some sort of callback that performs an action that results in you wanting to update your table)

 tableData = get(handles.uitable1, 'Data');
 tableData(:,2) = x;
 set(handles.uitable1, 'Data', tableData);

The assumptions are that your UI table is named uitable1 and that the number of rows in x is identical to the number of rows in the table (if not, then you can specify which rows of a certain column in the table you need to replace). For the purposes of this example, I'm replacing all of column 2 with x.
