Table view for VIKTOR applications
Project description
Table view (open-source view for VIKTOR)
This repository can be installed in a VIKTOR application to show nicely formatted tables.
Installation
Paste the link of this repository in your requirements.txt
:
viktor==14.4.0
viktor-table-view
Example implementation
The following could be an implementation of the TableView
(app.py
)
import numpy as np
import pandas as pd
from viktor import ViktorController
from viktor_table_view import TableResult
from viktor_table_view import TableView
class SampleEntity(ViktorController):
label = "SampleEntity"
@TableView("le view", duration_guess=1)
def le_view(self, **kwargs):
# Generate the data
data = np.random.randn(20, 6)
strings = np.array(["string1", "string2", "string3", "string4"])
string_data = np.random.choice(strings, size=(20, 4))
# Create the headers
headers1 = ["Text"] * 4 + ["Number"] * 6
headers2 = [f"Column {index + 1}" for index in range(0, 10)]
# Combine the headers and data into a dataframe
df = pd.DataFrame(np.column_stack([string_data, data]), columns=[headers1, headers2])
df.iloc[:, 4:] = df.iloc[:, 4:].astype(float)
df_colours = df.copy(deep=True)
df_colours.iloc[0, :] = "success"
df_colours.iloc[1, :] = "warning"
df_colours.iloc[2, :] = "error"
df_colours.iloc[3:, :] = pd.NA
return TableResult(df, dataframe_colours=df_colours, n_decimals={("Number", "Column 5"): 2})
