I am trying to format a LaTeX table (I am using ShareLaTeX online), and I want to do something special that I can't seem to figure out how to do. I think it involves using the multirow command but I am unsure. My code:

\begin{table}[h!] \centering \caption{VFD Parameter Settings (User and Basic)} \label{tab: VFD Parameter Settings1} \begin{tabular}{|l|l|l|p{3cm}|p{4.5cm}|} \hline Setting & Function & Value & Units/Description & Source/Reasoning \\ \hline \hline 00-10 & Control Mode & 0 & Speed Mode & To control speed \\ \hline 00-11 & Control of Speed Mode & 6 & PM Sensorless & (Open-Loop) For use with PMAC motors \\ \hline & & 4 & PM Vector + Encoder & (Closed-Loop) For Encoder control \\ \hline 00-20 & Source of Freq. Command & 0 & Digital Keypad & (Manual) Manually control freq. w/ keypad \\ \hline & & 5 & Pulse Input w/ Direction & (Auto) To control speed with Arduino pulses \\ \hline 00-21 & Source of Op. Command & 0 & Digital Keypad & (Manual) Manually control Start/Stop w/ keypad \\ \hline & & 1 & External Terminals & (Auto) To control Start/Stop with Arduino \\ \hline 00-23 & Control Motor Direction & 0 & Enable Fwd/Rev & Allow for both fwd and rev motion \\ \hline 00-32 & Keypad STOP function & 1 & STOP key enabled & Allows for STOP key to work in auto mode \\ \hline 01-00 & Max Operation Frequency & 200 & Hz & Frequency for rated speed of 3000RPM \\ \hline 01-01 & Output Frequency & *variable & Hz & (Open-Loop) Controls motor speed. Generally used 20-50Hz. \\ \hline 01-02 & Output Voltage & 115 & Vrms & Rated Bus Voltage from actuator nameplate \\ \hline 01-12 & Acceleration Time & *variable & seconds & Controls speed to ramp up. Used .05s. \\ \hline 01-13 & Deceleration Time & *variable & seconds & Controls speed to ramp down. Used .05s. \\ \hline 01-45 & Time Unit of Accel/Decel & 0 & 0.01 seconds & So accel/decel time is in units of 0.01s \\ \hline \end{tabular} \end{table}

This compiles as: enter image description here

For parameters 00-11, 00-20, and 00-21, I would like to combine and center the two rows of only the first two columns, eliminating the blank cells. I want to make it clear these parameters have two options depending on the control type. Here is an example of how I would like it to look from MS Excel: enter image description here

How do I go about doing this? I'm also aware the formatting in general isn't great, any other fixes you could recommend would be appreciated.

Use m for the last column and \multirow for the cells to be merged changing the respective \hlines to \clines.

\documentclass{article} \usepackage{array,multirow} \usepackage[margin=1in]{geometry} \begin{document} \newcommand*{\mr}[1]{\multirow{2}[4]{*}{#1}} \begin{table} \centering \caption{VFD Parameter Settings (User and Basic)} \label{tab: VFD Parameter Settings1} \begin{tabular}{|l|l|l|>{\raggedright}m{3cm}|m{4.5cm}|} \hline Setting & Function & Value & Units/Description & Source/Reasoning \\ \hline \hline 00-10 & Control Mode & 0 & Speed Mode & To control speed \\ \hline \mr{00-11} &\mr{Control of Speed Mode} & 6 & PM Sensorless & (Open-Loop) For use with PMAC motors \\ \cline{3-5} & & 4 & PM Vector + Encoder & (Closed-Loop) For Encoder control \\ \hline \mr{00-20} &\mr{Source of Freq. Command}& 0 & Digital Keypad & (Manual) Manually control freq. w/ keypad \\ \cline{3-5} & & 5 & Pulse Input w/Direction & (Auto) To control speed with Arduino pulses \\ \hline \mr{00-21} &\mr{Source of Op. Command} & 0 & Digital Keypad & (Manual) Manually control Start/Stop w/ keypad \\ \cline{3-5} & & 1 & External Terminals & (Auto) To control Start/Stop with Arduino \\ \hline 00-23 & Control Motor Direction & 0 & Enable Fwd/Rev & Allow for both fwd and rev motion \\ \hline 00-32 & Keypad STOP function & 1 & STOP key enabled & Allows for STOP key to work in auto mode \\ \hline 01-00 & Max Operation Frequency & 200 & Hz & Frequency for rated speed of 3000RPM \\ \hline 01-01 & Output Frequency & *variable & Hz & (Open-Loop) Controls motor speed.

  • Thank you very much! Great solution! Is there a way that I can avoid words being split in a cell and instead have them be in a new line in the cell? (Like En-coder in row 4 and Di-rection in row 6) Commented Jun 16, 2017 at 11:58
  • @RyanMcGrady -- Yes, just add >{\raggedright} before the p{3cm} column specification. Commented Jun 16, 2017 at 16:28

Here are some improvements and simplifications:
