[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 ={};

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)

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.

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
