Center text in a report

[#1]

I'm trying to center a report a created so the text is all centered instead of RTL for number and LTR for text

here is my code, dt is just a data table I tried using "Horizontal Alignment( "center" )" but it didn't work

[#2]

myPlatform = New Window( "Record Wafers",
modal,
myDispObj = dt << getAsReport,
myDispObj[Table Box( 1 )] << Set Scrollable( 0, 0 ) << Horizontal Alignment( "center" )
);

Assuming the text you mention is in a 'StringColBox()':

NamesDefaultToHere(1);

dt = Open("$SAMPLE_DATA/Big Class.jmp");
biv = dt << Bivariate( Y( :weight ), X( :height ), Fit Line );
repBiv = Report(biv);

Wait(3);
repBiv[StringColBox(1)] << setJustify( "center" );

thanks but it doesn't work here is my code again, i added the excel, hopefully you can show me what's wrong

dt = Open( "C:\Users\test.xls", "invisible" );
ob = Outline Box( "test", vl = V List Box() );
myPlatform = New Window( "test",
modal,
myDispObj = dt << getAsReport,
myDispObj[StringColBox( 1 )]<< setJustify( "center" );
myDispObj[Table Box( 1 )] << Set Scrollable( 0, 0 );
);

Using JMP 15.2 (on a Mac), with your code above I get (after stretching the column);

If I remove the 'setJustify()', I see:

I'm using jmp 12 ... but even in jmp 15 the "test2" and "test3" are still not in the middle, you can see "test2" is not center, but aligned to the right.
is there a way to center all the columns?
