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
------

With the function mentioned in my comments you'd go like this:

This is the function

CREATE FUNCTION dbo.CreateHTMLTable
(
    @SelectForXmlPathRowElementsXsinil XML
   ,@tblClass VARCHAR(100) --NULL to omit this class
   ,@thClass VARCHAR(100)  --same
   ,@tbClass VARCHAR(100)  --same
)
RETURNS XML
AS
BEGIN

RETURN 
(
    SELECT @tblClass AS [@class]  
    ,@thClass AS [thead/@class]
    ,@SelectForXmlPathRowElementsXsinil.query(
              N'let $first:=/row[1]
                return 
                 
                {
                for $th in $first/*
                return {if(not(empty($th/@caption))) then xs:string($th/@caption) else local-name($th)}
                }
                ') AS thead
    ,@tbClass AS [tbody/@class]
    ,@SelectForXmlPathRowElementsXsinil.query(
               N'for $tr in /row
                 return 
                 {$tr/@class}
                 {
                 for $td in $tr/*
                 return
                 if(empty($td/@link)) 
                 then {$td/@class}{string($td)}
                 else {$td/@class}{string($td)}
                 }
                 ') AS tbody
    FOR XML PATH('table'),TYPE
) 
END
GO

--Your test table

CREATE TABLE #tempo
(
    q1 INT, q2 INT, name VARCHAR(10)
);

INSERT INTO #tempo (q1, q2, name)
VALUES (10, 5, 'low'), (10, 10, 'same'), (10, 20, 'high');
GO

--Inline CSS for easy formatting

DECLARE @inlineCSS XML=
N'';

--This is the actual query

SELECT @inlineCSS 
      ,dbo.CreateHTMLTable
        (
             (
             SELECT 
               CASE WHEN ISNULL(q1,0)>ISNULL(q2,0) THEN 'low' 
                    ELSE CASE WHEN ISNULL(q2,0)>ISNULL(q1,0) THEN 'high' 
                         ELSE 'same' 
                         END 
                    END AS [@class] 
              ,name AS Material
              ,ISNULL(q1,0) AS [Q1]
              ,ISNULL(q2,0) AS [Q2]
             FROM #tempo 
             FOR XML PATH('row'),ELEMENTS XSINIL),NULL,NULL,NULL
        )
FOR XML PATH('body'),ROOT('html');

--Hint: Using classnames instead of the three ,NULL,NULL,NULL allows to place general CSS classes to the

, the and the .

--Clean-Up

GO
DROP TABLE #tempo
GO
DROP FUNCTION dbo.CreateHTMLTable;

This is the result (click "Run" to see the output)

Material	Q1	Q2
low	10	5
same	10	10
high	10	20
