HTML not displaying correctly in email sent with PowerShell

Question

I have a script which displays disk space on all servers on a HTML page and side by side sends email from the content of the HTML file saved.

The HTML file is perfect, and the email displays the tabular information same in the HTML file. However, the tables are overlapping in the email....

Code as below:

$freeSpaceFileName = "c:\script\FreeSpace.htm"
$serverlist = "c:\script\computers.txt"
$warning = 50
$critical = 30
New-Item -ItemType file $freeSpaceFileName -Force
# Getting the freespace info using WMI
#Get-WmiObject win32_logicaldisk  | Where-Object {$_.drivetype -eq 3} | format-table DeviceID, VolumeName,status,Size,FreeSpace | Out-File FreeSpace.txt
# Function to write the HTML Header to the file
Function writeHtmlHeader
{

This is happening because you don't close the <table> tag using </table> in your function writeDiskInfo.

To solve this, add the following just before the function close bracket :

Add-Content $fileName "</table>"

So, your function will look like this :

Function writeDiskInfo
{
 ......
 ......
 if ($freePercent -gt $warning)
 {
 .....
 }
 elseif ($freePercent -le $critical)
 {
 .....
 }
 else
 {
 .....
 }
 Add-Content $fileName "</table>"  # <--- ADD THIS HERE !
}

Seems that browsers are more permissive about syntax errors than mail clients ;)

What KrisFR has said is correct that you need to add end of table command but he mentioned it wrongly. You need to add in the writeHtmlHeader function just before the end parentheses of the function.

writeHtmlHeader $freeSpaceFileName

foreach ($server in Get-Content $serverlist)

{

...
...

foreach ($item in $dp)

{

...
...

}

Add-Content $fileName " /table>" # <--- ADD THIS HERE !

}
