Ag-Grid component with input support

Sorry, the deletion function test failed. I am not familiar with JS

Thanks for bringing this up. When I have used text wrapping in this excellent component with auto height in the cell contents, I find that the text breaks within the words rather than at spaces between words:

Is there a way to fix this via setting white-space: normal; so that line breaks only occur between words? The blog for Ag-Grid includes some detailed template information for the header rows but not the cell contents:

Thanks @Max_Witteman for the great solution.
One side note for the delete function, I had to add to its ‘configure_column’ the parameter ‘checkboxSelection=True’ so that user can use it to select the row to delete.

anyone can help me?
i need chance cellstyle based on a conditional, but, i dont know how i’ll do this.

i know how define a conditional on pandas, but not on ag grid

i am trying to add image field into my Ag-Grid object by following this example but with success.
i am retrieving data from SQL server and convert it to dataframe than try to add the image but is not working.
i mage exist on my drive

where is my error ?


           var element = document.createElement("span");
            var imageElement = document.createElement("img");
            if ( {
                imageElement.src =;
            } else {
                imageElement.src = "";
            return element;
    gb.configure_column('pic', cellRenderer=show_image)

it depends on the field name or column that you want to make a condition for it let say based on your post you want to change the color or the record based on the field name ESTOQUE

inside the Ag-Grid object you need to follow these steps.

let say you have a datafarme df


from st_aggrid import GridOptionsBuilder,JsCode
dg = GridOptionsBuilder.from_dataframe(df)
change_color = JsCode("""
            if( ====4){
                   return {
           if( ====2){
                 return {

gridoptions =

grid_table = AgGrid(df,gridoptions, allow_unsafe_jscode = True)

Hi @Max_Witteman , I’m interested to know how you implemented default values for added rows and also the pop confirmation for delete button. Thank you so much!

Hi, I am trying to use a list inside JScode to check my if condition. But whenever I pass the the list, all the values of the data frame disappear. How can I use a list to check if my params.value equals to one of the value in the list, rather an a single value.

value = [1,2]
cellstyle_jscode = JsCode(f"""
const error = {value}   
    function (params) {{  
        const hasValue = error.includes(params.value)          
            if (hasValue === true){{
                return {{
                    'backgroundColor': 'red',

gb = GridOptionsBuilder.from_dataframe(failed_indices_df)
gb.configure_columns(failed_indices_df, cellStyle=cellstyle_jscode,)
gridoptions =
response = st.write(
        fit_columns_on_grid_load =True,

Local images need to be base64. Here’s an example you can test out (Display images in AgGrid table - #8 by Shawn_Pereira).


I tried your answer with the connection with SQL server DB the picture doesn’t show in the AgGrid table.
But if i tried to read the image based on the giving path it works and the ReadPictureFile() return the correct file.

Note: if i try your code it works perfectly with the giving dataframe but once i tried to use it inside my SQL table it crash and doesn’t display the picture.

what could be the problem and how to display image inside the AgGrid table i needed in order to accomplish my project.

Well, I don’t have SQL server DB nor have access to your data.

Just before your “if df.shape[0]…” statement, insert a st.dataframe(df) to check what comes back from the database into your ImgPath column of your data frame.

If valid image paths come back, do they actually point to the exact image location? You will need to test this.

Also, does your ImgLocation column correctly classify the image as ‘Local’ for the image that resides on your disk?


Is there currently any support for server side row models? I was hoping to use this for something large enough that the data table might get too large for the 200 MB max that streamlit will take in a single table. Luckily, aggrid has a tool for this sort of situation, but I’m struggling to figure out if/how I can accomplish this with this package.

Does anyone have any ideas?


looking at one of the examples it appears the grid needs to be set to rowModelType: ‘serverSide’

Srry though I haven’t attempted an example I’m still trying to get my aggrid to work with immutable data…
JavaScript Data Grid: Updating Row Data …once I get that done I’ll attempt larger data sets and get back…but for extremely large data sets I would think for interim to filter out data before sending to grid with options to then select which buckets of data to view (user selects which bucket when data has to be sliced up)

Thanks for the response.
Yes, I agree that the grid option “rowModelType” needs to be set to “serverSide”, but that is not the only piece. In particular, in looking into it more, it seems we need to be able to set the ServerSideDatasource to be able to retrieve new rows.
(For example: if you were to create the aggrid in JS, I think you would need a line like
function ServerSideDatasource() {}
ServerSideDatasource.prototype.getRows = function (params) {
gridOptions.api.setServerSideDatasource(new ServerSideDatasource());
As far as I can tell, there isn’t anything currently built into this module to allow that. Moreover, when I look at the st_aggrid source code, it appears it has been manually set to only take client side row models, but I would be happy to be wrong!

Hi, Is there anyway to display the full contents of a cell in Ag-Grid when we click on it. My cell contents are too big. Resizing the columns of the table will make it less convenient for the user.

I’m looking for something like the second picture(normal st.dataframe). Displaying full cell contents when clicking on it

Ag-Grid table

Thanks! :slight_smile:

Hey Kiran, I have a couple ideas for hacks for this.

The closest thing to what you are looking for is probably the onCellClicked grid option. This option can take some JsCode that will be executed whenever a cell is clicked. I don’t know javascript well enough to tell you what that code should be, though. Using the GridOptionBuilder, this would look something like:
gb.configure_grid_options( onCellClicked = JsCode(“”“function(event) { <your code> }”“”) )

The second idea would be to mess with the master-detail stuff. The aggrid documentation for this is here. To use this for st_aggrid, you can use the gridOptionBuilder to set the option masterDetail to True, and set detailCellRendererParams to a dictionary which at least includes “getDetailRowData” : <Some JSCode to access the text>.

This may look something like:
“detailGridOptions”: {
“columnDefs”: <your code>,
“getDetailRowData”: JsCode(“”“function(params){

Not sure if that is exactly right because VulnerabilityImpact column has just strings instead of its JSON objects, but you can probably figure it out from there.

Finally, I think there might be grid options that works like onCellClicked but for double click and right click, but I don’t remember their names or how they work.

Thank you all for this! Just wondering, is grouping and hovering enabled from this package?

ag-Grid Styling & Appearance: Row Styles

Hi @crsca, you can try out my sample code for grouping as below, and modify it for your use thereafter:

import pandas as pd
import streamlit as st
from st_aggrid import JsCode, AgGrid, GridOptionsBuilder
from st_aggrid.shared import GridUpdateMode

df=pd.DataFrame({ "Name": ['Paul', 'Gina'], "Age": [43, 35], "Inducted": [True, False], 
                  "Firm": ['Google', 'Microsoft'], "JDesc": ['Analyst', 'Programmer']})
gridOptions = GridOptionsBuilder.from_dataframe(df)
gb =

gb['columnDefs'] = [ { 'headerName': 'Personal Dtls', 'children': [ { 'field': 'Name' }, { 'field': 'Age' } ] }, 
                     { 'headerName': 'Partially', 'children': [{'field': 'Inducted'}] }, 
                     { 'headerName': 'Profession Dtls', 'children': [ { 'field': 'Firm' }, { 'field': 'JDesc' } ] }, 
                     { 'children': [{'field': 'Processed'}] } ]
dta = AgGrid(df, gridOptions=gb, height=350, theme="blue", update_mode=GridUpdateMode.SELECTION_CHANGED)

@Shawn_Pereira this worked perfectly! Thank you!

Just a quick follow up, how would you center the header names and is it possible to customize their background color?

I tried adding headerClass and cellClass, and still no luck.

gb[“columnDefs”] = [
“headerName”: “Personal Dtls”,
“headerClass”: “ag-center-header”,
“cellClass”: “ag-center-cell”,
“children”: [{“field”: “Name”}, {“field”: “Age”}],
{“headerName”: “Partially”, “children”: [{“field”: “Inducted”}]},
“headerName”: “Profession Dtls”,
“children”: [{“field”: “Firm”}, {“field”: “JDesc”}],
{“children”: [{“field”: “Processed”}]},
