title: Align text when using tableGrob or grid.table in R
body: <p>When creating a table using tableGrob or grid.table.
  Is there way to align the text inside the table? First column to the left, and the other columns to the right? Rather than the default "center".</p>
  
  <p>Thank you!</p>
  
  <p>something like this: where I want column "a" alligned to the left.</p>
  
  <pre><code>a &lt;- c("one","two","thirty five")
  b &lt;- c(1, 2, 3)
  c &lt;- c(4, 5, 6)
  
  data &lt;- data.frame(a,b,c)
  
  windows()
  
  grid.table(
    data,
    gpar.coretext=gpar(fontsize = 12),            
    gpar.coltext = gpar(fontsize = 12),            
    gpar.rowtext = gpar(fontsize = 12),            
    gpar.corefill = 
      gpar(fill = "green", alpha = 0.5, col = NA),           
    h.even.alpha = 0.5,            
    equal.width = FALSE,            
    show.rownames = FALSE,            
    show.vlines = TRUE,           
    padding.h = unit(15, "mm"),            
    padding.v = unit(8, "mm")            
  ) 
  </code></pre>
