Split Columns allow you to divide a section of the page into columns with or without a border. Please note, this is not the same as a table as these columns are to be used for layout, not tabular data.
Make an inline table that is one row deep, and enter the number of columns you need.
Choose the table style from the drop down list that matches the number and style of the columns you want: 'split 2 column', 'split 3 column border', 'split 4 column' etc.
Enter text and pictures as normal. You can still float pictures inside the columns using 'image left' and 'image right'.
The example below has been made by selecting split '3 column border'.
