Sure, that is as good a way as any to change columns.

In Excel, there is no need to change the number of columns, just move left or right (or change the percent of view) on the page.
Adding newspaper columns to a Microsoft Word document is simple. Having opened a new document, select "Format" from the main menu and "Column" from the drop-down list provided. A new menu box will open and from here you will be able to select the number and style of columns required. In more recent editions of Microsoft Word, the process is simpler still. Using the "ribbon" select "Page Layout", then click on the "Columns" button. This will open the column settings menu box described above.

The answer to the question of which column corresponds to which button (selections) is that it depends on how the vending machine is programmed. Each button can be programmed to correspond to any of the 12 columns. This allows you to have multiple columns of Coke or Pepsi for instance and have all two or three columns linked to the one button. Your best bet on learning how to program the machine properly is to get a manual. If you do not have a manual but still want to operate it 'as is', you can test by placing different products in each of the columns. Push the selections and see what comes out from each button. As to refilling machine, it also depends on whether you have it set up for cans or bottles. If it is set for bottles, then the tops of the bottles always point to the outside of the machine. Thus the front row tops point to the front of the machine and the back row tops point to the rear of the machine. If set for cans, it won't matter which end is which although the machines usually have a diagram on the door with recommendations as to the best way to 'set' the cans.
Yes, that is normally what happens. However, there are exceptions. For example, you can select a column of numbers and when you click Autosum, it will put a total in the cell below the column. It is also possible to have it entered in more than one cell. For example, if you have a group of columns with numbers, you can select the line of cells below those columns or all of the columns. There will still only be one active cell, but clicking the Autosum button will put a total under each column.
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.
Yes, you can do that. If you have a series of columns, you can highlight all of the column to select the range. When you click on the auto-sum button, Excel will insert =SUM(XX:XX) at the bottom of each column in the range.
You can do it through the Insert Table option on the Table menu, or using the icon on the Standard toolbar. You can then choose the amount of columns and rows you want in the table and if it has numbers in them ... don't worry.... backspace each one
