round two decimal in table app designer

            [app.UITableFilteredTable.Data]=Table_HistoricalTable_Struct(app.Eq);
           x = [{90} repmat({60},1,size(app.UITableFilteredTable.Data,2)-1)];   
            app.UITableFilteredTable.ColumnWidth =x;
            app.UITableFilteredTable.ColumnName ={};
            
            

i try to use : round(v*100)/100 in table field's but it doesn't work

A random matrix:

M = rand(10,2);

A uitable showing that matrix (defaults to 4 decimal places):

figure()
uitable('Data',M);

Another uitable with the numbers rounded to two decimal places:

figure()
uitable('Data',round(M,2));

Another uitable with rounded data, using character vectors instead of numbers:

figure()
t = uitable('Data',compose('%.2f',M),'ColumnFormat',{'char','char'});

Since you are using a uifigure, you can also add a uistyle to the uitable that sets the HorizontalAlignment of the text to the right.

s = uistyle('HorizontalAlignment','right');
addStyle(t,s)

i try this:

   [app.UITableFilteredTable.Data]=Table_HistoricalTable_Struct(app.Eq);
           x = [{90} repmat({60},1,size(app.UITableFilteredTable.Data,2)-1)];   
            app.UITableFilteredTable.ColumnWidth =x;
            app.UITableFilteredTable.ColumnName ={};
            app.UITableFilteredTable.ColumnFormat =repmat({'char'},1,size(app.UITableFilteredTable.Data,2)-1); 

Warning: 'ColumnFormat' value has no effect when 'Data' value is a table array.

Warning: 'ColumnFormat' value has no effect when 'Data' value is a table array.

and where i can i write it ? (compose('%.2f',M),)

Since your uitable's Data is a table, I think you'll have to change the data in the table variable itself.

T = Table_HistoricalTable_Struct(app.Eq);

str = compose('%.2f',T{:,2:end});
T = convertvars(T,T.Properties.VariableNames(2:end),'cell');
T{:,2:end} = str;

app.UITableFilteredTable.Data = T;

Note that now the data in columns 2-end of your uitable is character vectors instead of numbers, and if you convert it to numbers again, e.g., to do some calculation with it, you've lost precision beyond 2 decimal places. In other words, you are changing the actual data in the table, not just how it's displayed. I don't know of a way to change the display without changing the underlying data.

hi,it's possibile to set HorizontalAlignment all element but not column n.2?

[Voss]

Yes

t = app.UITableFilteredTable; % your uitable

s = uistyle('HorizontalAlignment','center') % 'center' or whatever you want them to be

addStyle(t,s,'column',[1 3:size(t.Data,2)]) % add style s to columns 1 and 3:end of uitable t
