Enclose your code with the html and body tags. Size attribute does not correspond to font-size and it looks like its domain does not go beyond value 7. Furthermore font tag is not supported in HTML5. Consider this code for your case
<!DOCTYPE html> <html> <body> <font size="2" face="Courier New" > <table width="100%"> <tr> <td><b>Client</b></td> <td><b>InstanceName</b></td> <td><b>dbname</b></td> <td><b>Filename</b></td> <td><b>KeyName</b></td> <td><b>Rotation</b></td> <td><b>Path</b></td> </tr> <tr> <td>NEWDEV6</td> <td>EXPRESS2012</td> <td>master</td><td>master.mdf</td> <td>test_key_16</td><td>0</td> <td>d:\Program Files\Microsoft SQL Server\MSSQL11.EXPRESS2012\MSSQL\DATA\master.mdf</td> </tr> </table> </font> <font size="5" face="Courier New" > <table width="100%"> <tr> <td><b>Client</b></td> <td><b>InstanceName</b></td> <td><b>dbname</b></td> <td><b>Filename</b></td> <td><b>KeyName</b></td> <td><b>Rotation</b></td> <td><b>Path</b></td></tr> <tr> <td>NEWDEV6</td> <td>EXPRESS2012</td> <td>master</td> <td>master.mdf</td> <td>test_key_16</td> <td>0</td> <td>d:\Program Files\Microsoft SQL Server\MSSQL11.EXPRESS2012\MSSQL\DATA\master.mdf</td></tr> </table></font> </body> </html>
