'Units', 'normalized', ...
'Position', [0.05, 0.01, 0.3, 0.98], ...
'CellSelectionCallback', @(src,evnt) PPTableButtonDownCallback(src, evnt, this), ...
'CellEditCallback', @(src,evnt) PPTableEditCallback(src, evnt, this))
here is code for the upodate of the tabel created ....the loop updates the rows with each event which is the click
ncols = 4;
data = cell(nItems, ncols);
for i =1 : nItems
data{i,1} = i;
data{i,2} = pointlist(i, 1);
data{i,3} = pointlist(i, 2);

columnname = {'#', 'x', 'y', 'no','id','Remove'};
columnformat = {[] [] [] {'value ', 'value2'} [] [] };
editable = [false true true true false false];
hTable.ColumnName = columnname;
hTable.ColumnFormat = columnformat;
hTable.ColumnEditable = editable;
hTable.RowName = [ ];
hTable.Data = data;
hTable.ColumnWidth = {60, 60, 60, 60, 60, 60};
