title: R- knitr:kable - How to display table without column names?
body: <p>Currently, I have this data frame (PS):</p>
  
  <p><a href="https://i.stack.imgur.com/xIL8j.png" rel="noreferrer"><img src="https://i.stack.imgur.com/xIL8j.png" alt="Table with column header"></a></p>
  
  <p>My code to display this table is:</p>
  
  <pre><code>kable(PS) %&gt;%
  kable_styling(bootstrap_options = c("striped", "hover", "condensed", "responsive"))
  </code></pre>
  
  <p>I want to display the table without column names like this:
  <a href="https://i.stack.imgur.com/eqQEF.png" rel="noreferrer"><img src="https://i.stack.imgur.com/eqQEF.png" alt="enter image description here"></a></p>
  
  <p>Problem is</p>
  
  <p>1) The column names should be non-empty, and attempts to use empty names will have unsupported results</p>
  
  <p>2) If I convert the data frame and remove the column names and then use kable like this:</p>
  
  <pre><code>PS.mat &lt;- as.matrix(PS)
  colnames(PS.mat) &lt;- NULL
  kable(PS) %&gt;%
  kable_styling(bootstrap_options = c("striped", "hover", "condensed", "responsive"))
  </code></pre>
  
  <p>I get the following error</p>
  
  <pre><code>Error in kable_info$colnames[[length(kable_info$colnames)]] : attempt to select less than one element in integerOneIndex
  </code></pre>
  
  <p>I also tried the following parameter but with no results</p>
  
  <pre><code>kable(PS, col.names = NA) 
  </code></pre>
  
  <p>EDIT 1:</p>
  
  <p>A reproducible example:</p>
  
  <pre><code>if (!require(pacman)) install.packages("pacman")
  p_load("lubridate","knitr","kableExtra","scales")
  
  Statistics &lt;- c("AUM",
              "Minimum Managed Account Size",
              "Liquidity",
              "Average Margin / Equity",
              "Roundturns / $ Million / Year",
              "Incentive Fees",
              "Instruments Traded")
  Value &lt;- c("$30K","$30K","Daily","50%","6,933","25%","ES")
  AI &lt;- data.frame(Statistics,Value);
  kable(AI) %&gt;%
  kable_styling(bootstrap_options = c("striped", "hover", "condensed", "responsive"))
  </code></pre>
