One way is to use a column formula including Loc Max() function to identify the column with maximum value.

Example:

// Make example table

dt = New Table**(**"test", add rows**(25****)**, <<**add multiple columns****(**"x", **4**, Numeric**))**;

For**(**i = **1**, i <= N Col**(**dt**)**, i++,

Column**(**i**)** << **Set Formula****(**Random Integer**(****10****))**

**)**;

// Identify the column with highest value for each row

dt << **New Column****(**"max x", Character, Formula**(**"x" || Char**(**Loc Max**(**Matrix**({**x1, x2, x3, x4**})))))**;

BTW: If you're not sure how to get to the Formula Editor to create a formula like this, choose **Cols->New Column... **and then choose **Formula** from the **Column Properties** drop down menu.
