In this example, we've selected cell B1 because we want to insert a new column between column A and column B. Right-click and select 'Insert' from the popup menu.
When the Insert window appears, click on the 'Entire column' selection and click on the OK button. A new column should now be inserted in the spreadsheet. In this example, we've inserted a new column into column B. All of the columns to the right of column B will be shifted to the right.
You can also create your list first and then insert the checkbox by selecting the adjoining empty column of cells. From the menu, click Insert > Tick box. To remove checkboxes, select the checkboxes you want to remove and press Delete. You can increase or decrease the size of the checkboxes by changing the font size from the toolbar. If you do not want it to do anything except show a 'tick' when you click it, go to the Developer tab and under controls click on 'Insert' In the Form Controls, click on the 'Check Box' item then 'draw' it in the cell (it is always a standard size) you want.
