Multiple table format through email using powershell

Question

Hi All,
I have a powershell script which executes a SQL Query on three SQL instances and provides the result in table format through email. The output email contains all the result of the query in a single output itself. Please help me, I have provided the code
which I am using
Sample output format which I am getting: 
ServerInstance
Databasename EnabledStatus
Instance1 Database1
Enable
Instance1 Database2
Enable
Instance1 Database3
Enable
Instance2 Database1
Enable
Instance2 Database2
Enable
My requirement is I should get two table formatted email like below:
Database status of Instance 1
ServerInstance
Databasename EnabledStatus
Instance1 Database1
Enable
Instance1 Database2
Enable
Instance1 Database3
Enable
Database status of Instance 2
ServerInstance
Databasename EnabledStatus
Instance2 Database1
Enable
Instance2 Database2 Enable

Generally it's best to post in the Hey Scripting Guy forum, they are scarily good in there. Someday i hope to give an answer so perfect that not even jrv can improve on it.
Your approach might be possible but it's not the way i'd do it. The ConvertTo-HTML is pretty clever, it works well with arrays of objects. If you were to load each result into a custom PSObject then add that to an array of them for later processing you can
get the table formatting almost for free.
I haven't worked with SQL queries in a bit but this might work, it seems ok when i put token results in for the SQL result.
