Allow styling of table component rows/columns

[richard-to]

Need to determine a way to enable styling of table rows/columns.

Some use cases from user feedback:

1. Highlight selected row / cell
2. Alternate coloring of rows

There are are also other use cases for being able to control color, such as if a cell coloring based on the value.

Can we use state-driven styling for this??

Additional use cases:

• Highlight a row on hover
• Tooltip (i.e. abbreviated text shown in full)

Most interested in eventually having the 'expandable row' feature from https://material.angular.io/components/table/examples

This should help tremendously with the master/detail workflows.

Table rows are currently centered horizontally, it would be good to be able to change the alignment, too, to top or bottom
