I have 2 scripts script1 has the following: $exportObject = New-Object System.Collections.ArrayList $exportObject | Select-Object in script2, i am calling script1 to do something

Solution 1:

You can be as creative as you like with HTML styling of course. Below code styles the table like this:

# just some fake data here$exportObject = @(
    [PSCustomObject]@{
        'Server' = 'Server1.com''Cube' = 'Cube1''Connection Details' = 'Connection changed!'
    },
    [PSCustomObject]@{
        'Server' = 'Server2.com''Cube' = 'Cube2''Connection Details' = 'Connection Unchanged!'
    },
        [PSCustomObject]@{
        'Server' = 'Server3.com''Cube' = 'Cube3''Connection Details' = 'Connection changed!'
    }
)

functionConvertTo-HTMLTable ($obj) {
    # Accepts a System.Data.DataTable object or an array of PSObjects and converts to styled HTML table# add type needed to replace HTML special characters into entities
    Add-Type -AssemblyName System.Web

    $sb = New-Object -TypeName System.Text.StringBuilder
    [void]$sb.AppendLine('<table>')
    if ($null -ne $obj) {
        if (([object]$obj).GetType().FullName -eq 'System.Data.DataTable'){
            # it is a DataTable; convert to array of PSObjects$obj = $obj | Select-Object * -ExcludeProperty ItemArray, Table, RowError, RowState, HasErrors
        }
        $headers = $obj[0].PSObject.Properties | Select -ExpandProperty Name
        [void]$sb.AppendLine('<thead><tr>')
        foreach ($column in $headers) {
            [void]$sb.AppendLine(('<th>{0}</th>' -f [System.Web.HttpUtility]::HtmlEncode($column)))
        }
        [void]$sb.AppendLine('</tr></thead><tbody>')
        $row = 0$obj | ForEach-Object {
            # add inline style for zebra color rowsif ($row++ -band 1) {
                $tr = '<tr style="background-color: {0};">' -f $oddRowBackColor
            } 
            else {
                $tr = '<tr>'
            }
            [void]$sb.AppendLine($tr)
            foreach ($column in $headers) {
                [string]$val = $($_.$column)
                if ([string]::IsNullOrWhiteSpace($val)) { 
                    $td = '<td>&nbsp;</td>' 
                } 
                else { 
                    $td = '<td>{0}</td>' -f [System.Web.HttpUtility]::HtmlEncode($val)
                }
                [void]$sb.Append($td)
            }
            [void]$sb.AppendLine('</tr>')
        }

        [void]$sb.AppendLine('</tbody>')
    }
    [void]$sb.AppendLine('</table>')

    return$sb.ToString()
}

Two examples to do table styling that mimic the MS Word Grid Table 5 Dark Accent 5 can be found here

Hope that helps

Solution 2:

Not sure what's going wrong for you. This works for me:

$Body = Get-ChildItem C:\Windows\ -File | 
    Select-Object -Property Name, Length, LastWriteTime -First 10 |
    ConvertTo-Html -As Table -Head '<style type="text/css">th,td { text-align:center; }</style>' |
    Out-String

Send-MailMessage -SmtpServer $SmtpServer -UseSsl -Subject $Subject -To $To -From$From -Body $Body -BodyAsHtml
