To see what is available, click the Insert tab, choose Table > Quick Tables and choose from a range of preconfigured tables such as calendars and tables with sub headings and other features.
Once the table is inserted into the document, you can replace the text in it with your own text such as the dates for your desired calendar month.
Most of the elements that you’re used to selecting from the Tables menu in previous versions of Word can be found on the Tables Tools > Layout tab and these include the ability to repeat header rows at the top of the table and options for adjusting the text direction and inserting and deleting rows.
Once you have a table formatted in the way you want it to look you can add that particular format to the Quick Tables Gallery so you can use it anytime.
To do this, click inside the table and choose Table Tools > Layout tab. Click Select > Select Table so the entire table is selected. Now, from the Ribbon, choose Insert > Table and click on the Quick Tables option.
Choose Save Selection to Quick Tables Gallery and the Create New Building Block dialog will appear. Complete it as you would for a regular Building block element with the exception that this time, leave the Gallery option set to Tables so the table will appears in the Quick Tables Gallery.
Click Ok when you’re done. In future, your custom designed table will be selectable from the Quick Tables Gallery.
