You cannot actually completely remove them so that the last column is Z. You can delete the content of them, but if you try to delete the columns themselves, they will still remain. Every worksheet has a fixed amount of rows and columns, and you cannot change that. You just use what you need.
Upgrade to Excel 2007 or higher. There is no way to increase the number of columns designed into the spreadsheet. Excel 2003 and earlier have a limit of 256 columns. Excel 2007 and higher has increased that to 16,000 columns.
Formulas will adjust when rows and columns are added or deleted.
To make changes to an entire column in excel, click on the column heading (letter at the top of the column) and make your desired changes.EXAMPLE (Make all text in column C align center):Click on the column "C" at the top of Column C. [This will highlight the entire column.]Click on the BOLD text formatting option. [You might need to click two or three times, if some text is bold and some is not.]Observe that all all text in Column C is bold.
When you open Excel, the grid-like screen you're looking at is a spread sheet. You can create/edit/delete/read other spread sheets in same document by referring to the bar at the lower end of the window.

This is the default behavior in most (all?) versions of Excel. You have to go out of your way to tell a spreadsheet NOT to do this.
Delete completely gets rid of a column. Columns to the right of it all move over. So if you deleted column D, column E would become column D. Hiding a column makes it disappear from view, but it is still part of the spreadsheet and can be hidden. If you hid column D, you would still see column C and to the right of it would be column E. You can still use cells in columns that are hidden in formulas.
It depends on if you want to delete only the contents of the column or remove the entire column from the worksheet. If you want to remove the entire column, right-click on the column heading and click on the delete menu option. If you want to leave the column, and delete only the contents, right-click on the column heading and press the Delete key.
Columns in an Excel table can be any width you like.
Spreadsheets existed before Microsoft Excel. Visicalc was the first one, launched in 1979. The first version of Excel came out in 1985. All that really happened then was that Microsoft now had a spreadsheet application. Microsoft Excel is now the most popularly used of the many spreadsheet applications.
You can never see all the columns and rows that there are as they are unlimited. However if you're trying to see all of the data you've entered, go to View->zoom->zoom out [the icon of the magnifying glass with the minus sign]
Calc (LibreOffice) and Excel (Microsoft) Lotus 1-2-3 (IBM) are all spreadsheet applications.
