Formating color in SQL Server using FOR XML PATH

Question

I already used this method, but now I have to use some colors depending on the values. So, I have the following information in a table:

Material | Q1 | Q2
------         


        

Answer 1

Here is another option. Not clear if you wanted just the one cell highlighted

EDIT - Updated for 3 colors

Example

DECLARE @html varchar(MAX)
SET @html = ''+
                    (
                    SELECT [td/@style] = 'background:'+choose(sign(q1-q2)+2,'blue;color:white;','yellow','red')
                          ,[td] = isnull(q1,0)
                          ,null
                          ,[td/@style] = 'background:'+choose(sign(q1-q2)+2,'blue;color:white;','yellow','red')
                          ,[td] = isnull(q2,0) 
                          ,null
                          ,[td/@style] = 'background:'+choose(sign(q1-q2)+2,'blue;color:white;','yellow','red')
                          ,[td] = name 
                     FROM #tempo
                    FOR XML PATH('tr')
                    )
                    +'

                    

                        
q1
                        
q2
                        
Compare
                    
'        
SELECT @html

Returns
