Set Colors In Pandastable

I am using python3.7 to create a table in a tkinter-window. For this table I would like to highlight certain cells/rows/columns. But I am just able to highlight columns via the sta

Solution 1:

I found this question searching answer for similar problem.

After digging in source code of setRowColors I found it can set every cell separatelly so you have to select columns using cols= because as default it uses cols=None

pt.setRowColors(rows=2, clr='blue',  cols=[1,3,5])

or you have to use "all" to select all columns

pt.setRowColors(rows=1, clr='green', cols='all')

---

As for pt.rowcolors - at start it is empty DataFrame without columns and rows and it has problem to set color correctly but if it used after setRowColors then it works correctly

    pt.setRowColors(rows=1, clr='green', cols='all')
    pt.rowcolors['date'] ='green'
    pt.rowcolors['label'][5] ='#dcf1fc'

---

Eventually you would have to manually create columns and rows rowcolors at start.

import pandas as pd
    import numpy as np

    for c in df.columns:
        if c not in pt.rowcolors.columns:
            pt.rowcolors[c] = pd.Series(np.nan,index=df.index)

from tkinter import *
from pandastable import Table, TableModel
import pandas as pd
import numpy as np

classMainClass(Frame):
    def__init__(self, parent=None):
        self.parent = parent
        Frame.__init__(self)
        self.main = self.master
        self.main.geometry('600x400+200+100')
        self.main.title('Overview trading pairs')
        f = Frame(self.main)
        f.pack(fill=BOTH,expand=1)
        df = TableModel.getSampleData()

        names = list(df.columns)
        pt = Table(f, dataframe=df, showtoolbar=0, showstatusbar=0)
        pt.show()

        pt.columncolors[names[4]] = '#dcf1fc'
        pt.columncolors['label'] = 'red'print('--- rowcolors ---')
        print(pt.rowcolors) # empty #pt.rowcolors['label'] = '#dcf1fc' # error #for c in df.columns:#    if c not in pt.rowcolors.columns:#        pt.rowcolors[c] = pd.Series(np.nan,index=df.index)

        pt.setRowColors(rows=1, clr='green', cols='all')
        pt.setRowColors(rows=2, clr='blue',  cols=[1,3,5])

        pt.rowcolors['date'] = 'green'#pt.rowcolors[ ['date','label'] ] = 'green'

        pt.rowcolors['label'][5] = '#dcf1fc'
        pt.rowcolors['label'][5,10] = '#dcf1fc'print('--- rowcolors ---')
        print(pt.rowcolors)
