Line Arrows for Tabular Integration Table

Question

I've recently reviewed this question to try to make a table for Integration by parts:

I tried using the code sample from it but LaTeX gives me a rendering error with the tikz arrows (and I don't know what it was so I just removed the tikz code entirely); however, it does not when I just use the table. My code is below:

    \documentclass{article}
    \usepackage{gensymb}
    \usepackage{graphicx}
    \usepackage[fleqn]{amsmath}
    \usepackage{amsfonts}
    \usepackage{amssymb}
    \usepackage[usenames,dvipsnames]{color}
    \usepackage{fullpage}
    \usepackage{cancel}
    \usepackage{easylist}
    \usepackage{booktabs}
    \usepackage{xparse}
    \usepackage{graphicx}
    \usepackage{tikz}
    \usepackage{framed} 
    \usepackage{tcolorbox}
    \usepackage[fleqn]{amsmath}
    \usepackage{framed,varwidth}
    \usepackage{enumitem, color, amssymb}
    \providecommand{\e}[1]{\ensuremath{\times 10^{#1}}}
    \begin{document}
    1. $\displaystyle{\int x^6\cdot e^x dx}$ \\
    \newline
    Make a table of u and its derivatives \& dv and its integrals...
   \[\renewcommand{\arraystretch}{1.5}
\begin{array}{c @{\hspace*{1.0cm}} c}\toprule
   D & I \\\cmidrule{1-2}
 x^6\tikzmark{Left 1} & \tikzmark{Right 1}e^x \\
  6x^5\tikzmark{Left 2} & \tikzmark{Right 2}e^x \\
  30x^4 \tikzmark{Left 3} & \tikzmark{Right 3}e^x \\
 120x^3  \tikzmark{Left 4} & \tikzmark{Right 4}e^x \\
 360x^2 \tikzmark{Left 5} & \tikzmark{Right 5} e^x \\
 720x \tikzmark{Left 6} & \tikzmark{Right 6} e^x \\
 720 \tikzmark{Left 7} & \tikzmark{Right 7} e^x \\
 0 \tikzmark{Left 8} & \tikzmark{Right 8} e^x \\\bottomline
\end{array}
\]

\DrawArrow{Left 1}{Right 2}{$+$}
\DrawArrow{Left 2}{Right 3}{$-$}
\DrawArrow{Left 3}{Right 4}{$+$}
\DrawArrow{Left 4}{Right 5}{$-$}
\DrawArrow{Left 5}{Right 6}{$+$}
\DrawArrow{Left 6}{Right 7}{$-$}
\DrawArrow{Left 7}{Right 8}{$+$}
\end{document}

Is there an alternative to the post I linked to make the arrows & the plus or minus signs?

Er... well... what error? If this is due to differing versions of PGF, one alternative (to not having arrows) is to (1) update the code or (2) update your system (whichever is applicable). — cfr, Feb 01 '15 at 01:28
Are all those packages really necessary to help you? Will I not be able to reproduce the problem if I don't have them all installed? [It surely isn't necessary to load half of them twice, in any case.] — cfr, Feb 01 '15 at 01:28
I can edit my post to include all my code so it can be rendered but it'll be a little more lengthier...it must be clashing with something else in my document. Would you like the full code? — cbutcher12, Feb 01 '15 at 01:29
No. We need a minimal working example (MWE) that illustrates your problem. Note that there is a second solution using pstricks. So that's another alternative. Also, tikzmark is now available as a TiKZ library. — cfr, Feb 01 '15 at 01:32
I used the code from the previous example and rendered it again and it worked so must be a typo on my part...however, I wanted to add more to the chart so I changed the code to compensate and I've edited my post but now I'm getting an error again. Could you advise? — cbutcher12, Feb 01 '15 at 01:44
Never mind, the \bottomline was giving me an error...I removed it and it rendered fine. — cbutcher12, Feb 01 '15 at 02:11

Here is the corrected version of your code:

enter image description here

Changes:

Included the required \tikzmark, \DrawArrow and related macros from the linked question and eliminated the unnecessary packages.
Used enumerate to number it -- am assuming that there may be more.
Added trailing % following the calls to \DrawArrow.
Used \dots instead of ....
Replaced \bottomrule with \bottomline.

I apologize for accidentally not clicking the green arrow from Feb. 7th at 1:51... — cbutcher12, Jun 11 '15 at 07:18
(Just got here via a recent link on twitter) note that tikzmark is now a tikz library and it is better to use the library version than old versions of the command that don't have its snazzy new features. — Andrew Stacey, Jun 11 '21 at 15:54

With {NiceArray} of nicematrix and Tikz.

You need several compilations (because of the PGF/Tikz nodes).
