Would be great to have basic formatting properties for tables. Cell color is not enough to create certain data visualizations.

• Stroke properties: color, weight, line type (dashed, solid)
• Merge cells: just a must
• Drop shadow: for table as a whole. At least in design mode
• Headers: ability to select hoe many rows to display as header
• Footers: same as headers
• Alternating colors
• Basic filtering or tagging
• Support in design files
