    resolved [RESOLVED] Change color of text in table printed by Javascript

    So, this table took me forever to get to print right. I had to scan a few other tables I found online to get it right. Here's what I ended up with:

    PHP Code:
    var numRows 12
    var numCols 12

        
    var tblPrint ""rowPrint
        for (var 
    row 0row <= numRowsrow++) { 
            
    rowPrint ""
            for (var 
    col 0col <= numColscol++) { 
                if (
    row == 0) { 
                    
    rowPrint += "<td><strong>" 
                        ((
    col == 0) ? " " col) + 
                        
    "</strong> </td>"
                } else if (
    col == 0) { 
                    
    rowPrint += "<td><strong>" 
                        
    row 
                        
    "</strong> </td>"
                } else { 
                    
    rowPrint += "<td>" 
                        (
    row col) + 
                        
    "</td>"
                } 
            } 
            
    tblPrint += "<tr>" rowPrint "</tr>"
        } 
        
    document.write("<table border=\"1\">" 
            
    tblPrint 
            
    "</table>"); 
    Now, I need to add to it, but I don't know anything about adding color in Javascript. I want to get the outside numbers of the table (the ones being multiplied) to be blue. Then, I wanted the squared numbers (The values received from multiplying two of the same numbers, eg: 1x1=1, 2x2=4, 3x3=9 - 1,4,9, would be red on the table). Anyone think they can tackle this? It'd be appreciated!

    I won't really mess around with any structure to what you have since it does work. You are already checking for the 'outside numbers' so applying a color to those is easy. There was one additional if() statement I had to add in order to check for squared numbers but that was fairly simple on a table like this.

    Code:
    var numRows = 12;
    var numCols = 12;
    
    var tblPrint = "", rowPrint; 
    for(var row = 0; row <= numRows; row++) { 
    	rowPrint = ""; 
    	for(var col = 0; col <= numCols; col++) { 
    		if(row == 0) { 
    			rowPrint += "<td style='color: #00F;'><strong>" + 
    				((col == 0) ? " " : col) + 
    				"</strong> </td>"; 
    		} else if(col == 0) { 
    			rowPrint += "<td style='color: #00F;'><strong>" + 
    				row + 
    				"</strong> </td>"; 
    		} else {
    			if(row == col) {
    				rowPrint += "<td style='color: #F00;'>" +
    					(row * col) +
    					"</td>";
    			} else {
    				rowPrint += "<td>" +
    					(row * col) +
    					"</td>";
    			}
    		}
    	}
    	tblPrint += "<tr>" + rowPrint + "</tr>";
    } 
    document.write("<table border=\"1\">" +
    	tblPrint +
    	"</table>");

    Sup3rkirby, I should make you a shirt that says, "Super Javascriptman!" or something of the sort. This was excellent! Thank you again.
