I am trying to center the text inside a matplotlib table cell, while the default seems to be right aligned. I looked through the documentation of the Table object, but I could not find anything useful in this.
Is there an easy way to achieve the centering?
Try editing the sample here
Adding
cellLoc='center'
To
the_table = plt.table(cellText=cell_text,
rowLabels=rows,
rowColours=colors,
colLabels=columns,
loc='bottom')
To get
Another answer which edits the cell's alignment individually, serves this case and a more general one where only arbitrary columns (but not all) are to be centered (or any specific cells to that case).
Let's say you have a 5 rows - 3 columns table. If you want to edit only first column:
the_table = plt.table(cellText=cell_text,
rowLabels=rows,
rowColours=colors,
colLabels=columns,
loc='bottom')
cells = the_table.properties()["celld"]
for i in range(0, 5):
cells[i, 0]._loc = 'center'
I was stuck with this until I took a look at table.py source
EDIT 10/24/2021: As of today the above approach doesn't seem to work. It is however easy to fix it using set_text_props method of Cell objects (don't know if it didn't exit back then or I was unaware of it). To test it just add the following lines before the plt.show() of the official table demo. In this case the 4th column is centered.
cells = the_table.properties()["celld"]
for i in range(0, 5):
cells[i, 3].set_text_props(ha="center")
According to documentation, there is this metthod in cell object :
set_text_props(self, **kwargs)
kwargs may refers to text methods/attribute, such this one:
horizontalalignment or ha = [ 'center' | 'right' | 'left' ]
So, what about :
cell.set_text_props(ha='center')
Below method worked for me to change alignment for all cells.
col=5
rows=6
for i in range(0,col):
for j in range(1,rows):
cells[j, i].set_text_props(ha="center")
