Troubleshooting Data Table Issues in Excel (7 Solutions)

Solution 1 – AutoCorrect Settings

• Data tables in Excel can automatically expand, but sometimes they fail to do so when new data is entered.

For example: 1-Sep is entered into cell B13, but the table has not been expanded.

• To fix this, adjust the AutoCorrect Options:
  • Click File > Options > Proofing > AutoCorrect Options.

• • Go to the AutoFormat As You Type tab.
  • Check the boxes for:
    • “Include new rows and columns in table” (in the Apply as you work section).
    • “Fill formulas in tables to create calculated columns” (in the Automatically as you work section).
  • Press OK.

The table automatically expands when a new column or row is added.

Solution 2 – Table Functionality

• Data tables have features like sort and filter arrows, but sometimes they malfunction.

• To address this, convert the table to a range:
  • Select the entire data table.
  • Go to the Table Design tab.
  • Click Convert to Range and confirm.

The format of the data table will no longer change.

Solution 3 – Cells with Heterogeneous Characters 

• Ensure that all cells in the data table have consistent formatting.
• Right-click or press CTRL+1 to open the Format Cells dialog.
• Check the Locked option under Protection.

Solution 4 – Sheet Protection

• If the data table is on a protected sheet, unprotect it:

• • Go to the Review tab.
  • Click Unprotect Sheet.

Solution 5 – Sensitivity Analysis Issues (Same Value)

• Check the Calculation Options in the Formulas tab (ensure it’s set to Automatic).
• Link the value in the top-left cell (e.g., $1500) to the correct cell (e.g., =C10).

Solution 6 – Row and Column Input

• Be cautious with row and column inputs for What-If Analysis.
• Incorrect inputs can lead to unexpected results.

Solution 7 – Different Worksheets

• For sensitivity analysis, ensure the data table resides on the same worksheet.
• Cross-sheet references may cause unexpected outcomes.
