I created a table, which has four columns and fifteen rows. However, somewhat point, the angle column: 0,10,20,30,40,.... 120 is not displayed.

\caption{This table contains Cobalt's count rate:$R(\theta)$, count rate without background:$Y(\theta)$, and normalized count rate:$\frac{Y(\theta)}{Y(0)}$ their uncertainties. To obtain $R(\theta)$, divide "C" from Table.~\ref{Co_Count} by measured time, and its corresponding uncertainty:$\sigma R(\theta)$ is $\sigma C$ over time. For $\Y(\theta)$, subtract background count rate from$R(\theta)$. Its corresponding uncertainty is calculated by using Eq.~(\ref{eq:two}). Normalized count rate is divide $Y(\theta)$ by Y(0). Its uncertainty is from Eq.~(\ref{eq:one})}

Thank you in advance. Can you also explain what lcrr mean?
\\at the end of the rows. – egreg Dec 06 '19 at 22:48\\at the end of the rows, the angle column is displayed correctly. Also, thelcrrin argument oftabularis there to declare four columns to the table, the first being left aligned, the second being right aligned, and the two others being centered. – Vincent Dec 06 '19 at 23:02\end{document)cannot possibly work. – Mico Dec 07 '19 at 00:14
