Watch this video from MyOnlineTrainingHub and use it to practice Create and format Excel Tables and Table design for reporting.
Practice workbook setup
Create a rectangular dataset with headers, at least 20 rows, and one calculated column.
Practice workflow
- Convert the range to a table and give it a meaningful name.
- Add a calculated column and confirm the formula fills down automatically.
- Use structured references in one summary formula.
- Add new rows and confirm formulas, formatting, and references expand.
Quality checks
- Every column has a unique, descriptive header.
- The table name describes the data, not the sheet.
- Summary formulas still work after adding rows.
Common mistakes
- Leaving blank columns inside a table.
- Using vague table names like Table1 in important formulas.
- Turning a range into a table before fixing merged cells or broken headers.
Next actions
- Replace one normal range in an existing workbook with a table.
- Use the table as the source for a PivotTable or chart.
Formula focus: even if this workflow is not formula-heavy, add one check cell that confirms the final output still matches the source data.
