Simple question: Is there some way to merge table cells?

I'd like to create a 3×2 table with cells merged in this configuration

+----+----+----+
|    |    |    |
+----+----+    +
|         |    |
+----+----+----+

and in this configuration

+----+----+----+
|    |    |    |
+    +----+    +
|    |    |    |
+----+----+----+

To goal is to put a couple of widgets in there, where their arrangement relative to each other is easiest defined by a tabular layout with these relationships.

Sorry this is not possible. It is discussed in #3565 so I’ll close this issue as a duplicate.

Are your cell expected to be big? Depending on the amount/granularity of your contents it might make sense to use docking or resizable child windows to perform what you want.

It feels like you are trying to use tables as a bandaid for lack of better layout feature, so maybe we can come up with something better.

I see.

Yes, I'm attempting to layout rather large area stuff. Yesterday I spent some time attempting to get it done with the dock builder, but the logic to implement the responsive layouting I had in mind turned into a mess of hot garbage. Which is why I thought about doing it with a table.

Reizeable child windows? How does that work (I did not notice anything like that in the demo)?

For the moment I'll try the route of two nested tables – current comment in my UI code:

//	Two nested tables. Outer table (*) of 2 columns, with
//	an inner table (o) of 2 columns. Acquisition data (X)
//	either goes BELOW or at BOTTOM OF RIGHT column of (o)
//
//	*******************************************************
//	* ooooooooooooooooooooooooooooooooooooo *             *
//	* o          o                        o *             *
//	* o          o                        o *             *
//	* o          o                        o *             *
//	* o          o                        o *             *
//	* o          o                        o *             *
//	* o          o > Acquisition Data xxx o *             *
//	* o          o XXXXXXXXXXXXXXXXXXXXXX o *             *
//	* o          o XXXXXXXXXXXXXXXXXXXXXX o *             *
//	* o          o xxxxxxxxxxxxxxxxxxxxxx o *             *
//	* ooooooooooooooooooooooooooooooooooooo *             *
