I need to format my XSL file so that it will display data in a table with 2 columns. Eg:

Title: ABC
Age: 9
Level: 12
Grade: B

But my current display is:

Title:ABC
Age:9
Level:12
Grade:B

I have <DIV> and <SPAN> in my code. But I tried to use <TABLE> ,<TR>, <TD> .. etc. It just dun work :(

Show us your XML and XSL.

Something like this should work:
<table>
<xsl:for-each select="NodeID">
<tr><td> Title:</td><td>
<xsl:value-of select="Title"/>
</td></tr>
<tr><td> Age:</td><td>
<xsl:value-of select="Age"/>
</td></tr>
<tr><td> Level:</td><td>
<xsl:value-of select="Level"/>
</td></tr>
<tr><td> Grade:</td><td>
<xsl:value-of select="Grade"/>
</td></tr>
</xsl:for-each>
</table>
