Text Formatting ⇒ Alignment of Math Expression in a Table

[sachinrajsharma]

Hi,

I am facing the following error :

Code: Select all

! Extra alignment tab has been changed to \cr.

This is the problematic code.

Code: Select all

\begin{tabular}{|c|c|}\hline
  (I) If $\vec{a} =a_1\hat{i}+b_2\hat{j}+a_3\hat{k}; \vec{b}=b_1\hat{i}+b_2\hat{j}+b_3\hat{k}; \vec{c} =c_1\hat{i}+c_2\hat{j}+c_3\hat{k}$ then $[a b c ] $ &
  (B) $\begin{vmatrix}
        a_1 & a_2 & a_3 \\
        b_1 & b_2 & b_3\\
        \hat{i} & \hat{j} & \hat{k}\\
      \end{vmatrix}$
\end{tabular}

I am unable to locate the error please help thanks.

Please post a minimal working example that actually compiles and reproduces the problem. When I expand your snippet to the minimal working code (as below) it works fine, except it throws an overfull hbox warning because your table is very wide.

Code: Select all

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{tabular}{|c|c|}\hline
  (I) If $\vec{a} =a_1\hat{i}+b_2\hat{j}+a_3\hat{k}; \vec{b}=b_1\hat{i}+b_2\hat{j}+b_3\hat{k}; \vec{c} =c_1\hat{i}+c_2\hat{j}+c_3\hat{k}$ then $[a b c ] $ &
  (B) $\begin{vmatrix}
        a_1 & a_2 & a_3 \\
        b_1 & b_2 & b_3\\
        \hat{i} & \hat{j} & \hat{k}\\
      \end{vmatrix}$
\end{tabular}
\end{document}
