Feature request: Ability to change the text style and background colours of cells

[aiavci]

Summary

Currently the plugin only allows you to set the first row as bold if you select this option in the inline toolbar.

It would be really helpful to have the ability to change cell styles colours.

For example, We may want to make the background of the first column grey

Created one that allows modification of table and cell properties. Will add support for changing column and row styles

@YoofiBP this is amazing. I was only looking for text-alignment but your MR #88 adds many options.
