Environment

• TeXstudio: 4.8.5alpha1
• Qt: 6.7.2
• OS: Windows 11
• TeX distribution: miktex

Expected behavior

Tabularray tables are parsed correctly without reporting erroneous missing columns, and they can be aligned automatically.

Actual behavior

The following code triggers a missing column inspection on the newline marks and adds an invalid empty column when aligned.

Adding a linebreak after the colspec definition fixes the automatic alignment, but the inspection is not resolved.

\documentclass[letterpaper]{article}

\usepackage[sfdefault]{roboto}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[left=0.5in,right=0.5in,top=0.5in,bottom=0.65in]{geometry}
\usepackage{tabularray}

\begin{document}

\begin{tblr}{colspec = {Q[1,r,m]Q[1,l,m]},width = 0.4\linewidth,column{1} = {font=\bfseries}}
  Row 1 & Value 1 \\
  Row 2 & Value 2 \\
  Row 3 & Value 3 \\
  Row 4 & Value 4 \\
  Row 5 & Value 5 \\
  Row 6 & Value 6
\end{tblr}

\end{document}

How to reproduce

Open the above code in TexStudio:

1. Notice the invalid columns inspection is triggered
2. Automatically align it, and notice the extra column added
3. Undo the above and add a line break after the colspec:

   \begin{tblr}{colspec = {Q[1,r,m]Q[1,l,m]},
       width = 0.4\linewidth,column{1} = {font=\bfseries}}
     Row 1 & Value 1 \\
     Row 2 & Value 2 \\
     Row 3 & Value 3 \\
     Row 4 & Value 4 \\
     Row 5 & Value 5 \\
     Row 6 & Value 6
   \end{tblr}

4. Automatically align it, and notice no extra column is added
5. The inspection is still triggered
