If you want to add a row to an Excel spreadsheet, these are the simple steps you should take:
With your mouse, right click on the row header below where you want the new row to be added. Then, click Insert.
Follow exactly the same steps if you want to add a column to an Excel worksheet, right click on the column header, choose Insert and the new column will be inserted to the left of the selected column.
If you don’t want part of the Excel worksheet to be visible or when you don’t want certain data to appear in print outs, then a simple solution is to temporarily hide columns and rows.
Hide a single column:
1) Right click on the column header of the column you want to hide (this is the grey bar along the top edge of the worksheet)
2) Choose Hide from the menu
3) This column will now be hidden from view
Hide more than one column:
1) In the column header drag select to highlight the columns you want hidden
2) Right click and choose Hide from the menu
Hide separate columns:
1) Click on the fist column to be hidden
2) Press and hold down the CTRL key
3) While holding the CTRL key, left click on the rest of the columns you want to hide
4) Right click and choose Hide
Please note:- When you hide a column in an Excel worksheet, data in that column can still be used and referenced in the worksheet.
