Final answer:
If you select three columns in a worksheet and insert a sheet column, it will add a new column to the left of the selected columns.
Step-by-step explanation:
If you select three columns in a worksheet, click the Insert button arrow, and then click Insert Sheet Column in Excel, it will insert a new column to the left of the selected columns.For example, if you have columns A, B, and C selected, clicking Insert Sheet Column will add a new column beforcolumn A, shifting the existing columns to the right (B becomes C, C becomes D, and so on).
This can be useful when you want to add additional columns to your worksheet without overwriting or moving existing data.When you select three columns in an Excel worksheet, click the Insert button arrow, and then click Insert Sheet Column, three new, blank columns will be added to your worksheet. These new columns will appear immediately to the left of the first column you initially selected. Existing columns will shift to the right to accommodate the new ones. This feature is particularly useful for organizing and structuring data efficiently in your sheet without having to manually move data around.
