Sure, I can help you with that! Here's how you can "grey out" a row in Excel:

1. Select the row that you want to grey out.
2. Right-click on the selected row and choose "Format Cells" from the drop-down menu.
3. In the "Format Cells" dialog box, click on the "Fill" tab.
4. Choose the grey color that you want to use for the row by clicking on it.
5. Click "OK" to apply the formatting to the selected row.

Alternatively, you can also use conditional formatting to grey out a row based on a certain condition. Here's how:

1. Select the row that you want to apply the conditional formatting to.
2. Click on the "Conditional Formatting" button in the "Home" tab of the ribbon.
3. Choose "New Rule" from the drop-down menu.
4. In the "New Formatting Rule" dialog box, choose "Use a formula to determine which cells to format".
5. In the "Format values where this formula is true" field, enter a formula that will evaluate to TRUE for the rows that you want to grey out. For example, if you want to grey out rows where the value in column A is greater than 10, you can enter the formula
   Code:

   "=A110"

   (assuming that you have selected the first row of the table).
6. Click on the "Format" button to choose the grey color that you want to use for the row.
7. Click "OK" to apply the conditional formatting to the selected row.
