Please reproduce what you have done in an example on apex.oracle.com.
I have created an example on apex.oracle.com
I have set one page up using template (One Level Tabs - No sidebar) as a standard 26 theme.
Another page referencing (One Level Tabs - No sidebar(25)) as a standard 25 theme.
And a final page (One Level Tabs - No sidebar(26) with changes ) as a standard 26 theme with some changes to the template.

I am using Oracle Apex 4.2.1
I have been following a Youtube Video from Oracle Learning: http://www.youtube.com/watch?v=dPgQZTsdSBI
The video demonstrates an example of grid layout for regions. The layout has 12 columns and and 4 regions, the regions using 3 columns each. In the video the regions align perfectly.
I have tried to recreate this in theme 26 but it does not work.The theme 26 page templates are configured to use HTML table layout with a dynamic, variable number of columns. HTML tables expand to fit their contents, so the width of the columns is also variable.
I have set theme 26 to reference the page templates for theme 25.Don't know what you mean by this. Please explain in more detail.
However, this does not work and the regions appear next to each other using 1 grid each with no spacing.Basically there's nothing to "fix". This is how the table-based layout used in theme 26 works. The regions only appear to use "1 grid each" because their content is all the same size. If you add different content to the regions (as I have) then the table columns change width to fit it. You could use CSS to apply fixed widths to the columns, but that kind of defeats the purpose of using table-based layout.
Any ideas on how to fix this in theme 26?
The themes in APEX 4.2 don't appear to specify spacing between regions when using HTML table layout, but this can be controlled using CSS.
Why are you trying to use theme 26 rather than theme 25 as shown in the video demo? They don't look that different.
