我在R中绘制了一个复杂的热图，其中我将column_title和row_title指定为“k-mat”，但我只想用斜体显示k-mat中的“k”-如何在R中获得它？

library(ComplexHeatmap)
Heatmap(KI2, 
  col=custom_palette,
  show_row_dend=F,
  show_column_dend=F,
  show_row_names=F,
  show_column_names=F,
  heatmap_legend_param = list(title = "CNV"),
  column_title = "k-mat",
  column_title_side = "bottom",
  row_title = "k-mat",,
  row_title_gp = gpar(fontsize = 20),
  row_title_side = "left",
  column_title_gp = gpar(fontsize = 20)
)

字符串
以下是我的数据：

dput(KI2)

型
有可能吗？
