AppDesigner table not filtering properly

Hi, I am trying to create a button where I am able to filter my table based on my drop down (selects the column to filter) and edit field value (what text/value to look for). So far I have got something which filters the table but ticking the rows which meet my condition, however I would like for the table to ONLY show the filtered rows.

 i
% %Filter values based on drop down column select and journal edit field
%e.g. document type = GJ
app.FinalTable = strcmp(app.UITable.Data.(app.FilterDD),(app.JEditValue));
app.UITable.Data = app.FinalTable;

I have attached 2 image files: 1) Original table when I import the excel file: 2) Table once I filter the data (I want all rows where document type = GJ), essentially I want to figure out how I could get table to display data for those ticked rows
