Using Dynamic Variables in Velocity Templates

I am using velocity templates to generate email templates and here I want to create tables for each 'tag' with respective values as table data.

I am passing a List tags with details of the tags including tagName, using which I am passing the respective List for each tag. (If tagName = "test", I am passing the data for the test table as $test)

As shown I have set the data of each table to $arrayobjs, but the table does not display the rows as I think it doesnt iterate through the $arrayobs. Please help me iterate through the data and set the data to the coloumns.

P.S.-Although I am able to print the value of $tags[0] , $arrayobjs[0] does not print a value

    #set ($d = '$')                
        #foreach($tag in $tags)
        #set ($var = "${d}${tag.tagName}")
        #set ($arrayobjs = "#evaluate($var)")
            <table style='width:600px; padding-left: 11px; font:Segoe UI;'>
                <tr>
                    <td> <span style='font-size: 17px; font-weight: 400; font-family:Georgia;'>$tag.tagName </span></td>
                </tr>
                </table>
                <br>
                <table width=583 style='width:437.5pt; margin-left:8.25pt;border-collapse:collapse;font-family:"Segoe UI",sans-serif;'>
                    <tr  style='vertical-align:top;height:10px;'>

                        <td width=50px style='border:solid white 1.0pt;background: #a3a3c2;padding:1pt 1pt 1pt 1pt;'>

After almost 2 years I suggest the following answer :-)

#set ($d = '$')
#set ($h = '#')

#foreach($tag in $tags)
    #set ( $temp = "${h}set ( ${d}var = ${d}${tag.tagName} )" )
    #evaluate($temp)

    ## html code for table header

    #foreach($o in $var)
        ## table rows
    #end
#end
