Context: I have a div table that a client wants to be screen reader accessible like a regular html table is using the table commands
Problem: Cant get aria to work to announce the header with the row value to keep the integrity intact with the data.
Solutions: Only using div is it possible to make this accessible?
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
    .Table
    {
        display: table;
    }
    .Title
    {
        display: table-caption;
        text-align: center;
        font-weight: bold;
        font-size: larger;
    }
    .Heading
    {
        display: table-row;
        font-weight: bold;
        text-align: center;
    }
    .Row
    {
        display: table-row;
    }
    .Cell
    {
        display: table-cell;
        border: solid;
        border-width: thin;
        padding-left: 5px;
        padding-right: 5px;
    }
</style>

I don't know if this will actually work considering these roles are intended for real tables. Using an actual table would be a much better idea.
Anyway, your roles could be improved.
Looks like your
columnheadercontext is wrong. The header row should use therowrole:See: http://rawgit.com/w3c/aria/master/aria/aria.html#columnheader
Also, if this 'table' is not interactive you should use
role="table", notrole="grid". See note: http://rawgit.com/w3c/aria/master/aria/aria.html#gridIf the reason for the 'div table' is that you need a responsive table, see: https://css-tricks.com/responsive-data-tables/
