can a spreadsheet be filtered only by one column at a time?

No, a spreadsheet can be filtered by more than one column at a time. Many spreadsheet applications, such as Microsoft Excel and Google Sheets, allow users to apply filters on multiple columns simultaneously. By setting up filters on various columns, you can narrow down your data to meet more specific criteria across different data fields.

For example, if you had a spreadsheet with columns for "Name," "Age," and "City," you could apply a filter to show only entries for people over 30 years old (Age column) who also live in "New York" (City column). This would allow you to view a subset of your data that meets both conditions.

Here is how you might filter by multiple columns in a spreadsheet:

1. Click on the filter button or select the filter option from the data menu to enable filtering for the entire worksheet. 2. A drop-down arrow will appear in the header of each column. Click the arrow in the first column you want to filter. 3. Choose the filter criteria for the first column (e.g., a specific value, range of values, condition, etc.). 4. Repeat steps 2 and 3 for each additional column you want to filter by. 5. After applying filters to multiple columns, the spreadsheet will display only the rows that meet all the criteria you set.
