I don't think Ganesh understood the code he linked to, It is using HTML Agility Pack for a specific reason: parsing the table content, However, this case does NOT require that more sophisticated approach.

Assuming you need to access the web page online (offline would work like Shaun showed):
$ie = New-Object -com InternetExplorer.Application 
# $ie.visible = $true

# doing this is sufficient in most cases
while($ie.ReadyState -ne 4) { start-sleep 250 }

$count = @($ie.Document.Body.InnerText | select-string -pattern "<tr>.*</tr>").Count
