What problem does this address?

Currently I am unable to do the following in the table block:

• Style the Table headers separate from rest of the table, ie. different colors/fonts etc
• Style the Table footers separate from rest of the table, ie. different colors/fonts etc
• Style the Table caption separate from rest of the table, ie. different colors/fonts etc
• No way to merge cells with a colspan or rowspan without editing html
• No way to style individual cells separately from the column, ie. text align center for one cell, and left align for the rest. border, margin, etc for individual cells

What is your proposed solution?

Add support for these, maybe with some tool that is a cell selector under block style settings? Maybe we need child blocks such as table header block, table footer block, etc
