checklist:

• Use appropriate row height (not to much, make sure that data is easily comparible over rows/ clear overview)
• Use appropriate widths (if possible wide enough to not wrap headers, not to big to leave much space between columns)
• Numbers should be right-justified
• Dates should not be right-justified
• List-based filtering should only be used for columns of data that have less than 50 unique values, else use search based filtering.
• column header justification should match the data justification.
• aviod using embedded sections in columns (often cause of alignment/spacing issues)
