我正在尝试格式化 LaTeX 表格（我使用 ShareLaTeX online），我想做一些特别的事情，但我似乎不知道该怎么做。我认为这涉及使用多行命令，但我不确定。我的代码：
\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}
编译结果如下：
对于参数 00-11、00-20 和 00-21，我想合并并居中前两列的两行，消除空白单元格。我想明确指出这些参数根据控件类型有两个选项。以下是我希望它在 MS Excel 中显示的样子的示例：
我该怎么做？我也知道格式总体来说不太好，如果您能推荐其他修复方法我将不胜感激。
答案1
m对于最后一列和\multirow要合并的单元格使用将相应的\hlines 更改为\clines。
\documentclass{article}
