Remove rownames in gridExtra::tableGrob
<p>I would like to plot a table with ggplot, however cannot seem to manage to lose the row.names.</p>

<p>I have tried:</p>

<pre><code>row.names(cov_table_a)&lt;-NULL # outside the plot
row.names = FALSE            # inside the annotation_custom
</code></pre>

<p>This is my data:</p>

<pre><code>cov_table_a&lt;-
structure(list(Year = structure(1:16, .Label = c("1970", "1971", 
"1972", "1973", "1974", "1975", "1977", "1979", "1980", "1981", 
"1982", "1983", "1984", "1985", "1986", "1987", "1988", "1990", 
"1991", "1992", "2000", "2001", "2003", "2004", "2007", "2008", 
"2009", "2010", "2011", "2012", "2013", "2014"), class = "factor"), 
`Percentage \nof missing data` = structure(c(4L, 2L, 4L, 6L, 
1L, 12L, 5L, 21L, 21L, 11L, 10L, 13L, 9L, 17L, 18L, 14L), .Label = c("0%", 
"1%", "100%", "17%", "24%", "31%", "35%", "5%", "58%", "59%", 
"60%", "70%", "71%", "72%", "8%", "86%", "90%", "92%", "95%", 
"98%", "99%"), class = "factor")), .Names = c("Year", "Percentage \nof missing data"
), row.names = c(NA, -16L), class = "data.frame")
</code></pre>

<p>This how I try to plot it:</p>

<pre><code>library(ggplot2)
library(gridExtra)

# First I create an empty graph with absolutely nothing :
qplot(1:10, 1:10, geom = "blank") + theme_bw() + theme(line = element_blank(), text = element_blank()) +
# Then I add my table :
annotation_custom(grob = tableGrob(cov_table_a), xmin=-5, xmax=10,ymin=1, ymax=10)
</code></pre>
