Creating that kind of macro is not very difficult. For example:

Insert->Table->Plain tabular.
M-x (set-cell-background "broken white") enter [1].
Select the whole table then Edit->Cut.
Insert->Macro->Assign.
Type "yellowbg".
Press right arrow key.
Insert->Macro->Macro.
Type "body" then press Tab.
Paste the table we have cut before.
Press left arrow key (to get in the table cell).
Insert->Macro->Argument.
Type "body" then press Enter.
Press right arrow key (to get out of the table).
Press enter twice (to activate "macro" and "assign").

[1] that trick is required because the user interface does not yet
provide a way to use all the color defined in TeXmacs internals.

You have defined a yellowbg macro. But it is not yet satisfying
because it will not perform line breaking.

Move the caret after the invisible "assign".
Press backspace to deactivate "assign".
Press left arrow twice to move into the table.
Table->Special table properties->Use paragraph width.
Table->Special cell properties->Hyphenation->Top.
Press right arrow then enter twice to activate assign again.

Now you have what you wanted.

What is a bit trickier is creating macros which provide table
templates (like tabular, block, equnarray*, matrix).

TeXmacs is NOT a LaTeX front-end and is unrelated to emacs.
