I have implemented bootstrap 4 data table 4 in angular 4 but not able to change or modify row color. row selection color and header color as well.
I am using the data table 4 example : https://github.com/afermon/angular-4-data-table-bootstrap-4
and in this examples demo go through the demo 1 of link: https://afermon.github.io/angular-4-data-table-bootstrap-4-demo/
Considering the below code snippet present in data-table-component-demo1.ts got by the Git project you downloaded:
<data-table id="persons-grid"
[header] = "false"
[multiSelect] = "false"
[substituteRows]="false"
[indexColumn]="false"
[items]="items"
[itemCount]="itemCount"
(reload)="reloadItems($event)"
[pagination]="false"
(rowClick)="rowClick($event)"
[rowColors] = "callBackForChangineRowColors"
>
<data-table-column
[property]="'name'"
[header]="'Name'"
[sortable]="true"
[styleClass]="someExplicitClass"
In this, we can assign the value 'someExplicitClass' to [styleClass] as shown above and define the class someExplicitClass in our data-table-component-demo1.css file as below:
:host /deep/ .someExplicitClass{
background-color:red;
}
However, this is applied to the whole of the DataColumn and not controllable on a granular level.
We can indirectly apply only background-color using the rowEvent variable available within the rowClick(rowEvent) function of 'data-table-component-demo1.ts'
On click of the row, I will set the selected property of the row to true and thereby will trigger the onRowSelectChanged function of table.component.ts file
Now, once I set [rowColors] value to "callBackForChangineRowColors" as shown above and make the below changes in my data-table-component-demo1.component.ts file:
rowClick(rowEvent) {
console.log('Clicked: ' + rowEvent.row.item.name);
rowEvent.row.selected = true;
}
callBackForChangineRowColors(a,b,c)
{
if(b.selected)
return 'blue';
}
This way, I will be able to apply the color of blue explicitly for the selected Row.
*I could'nt unfortunately find any solution to apply any other styles on a granular level using a readily available input parameter like [styleClass] for it wasnt exposed as an #Input within our column.component.ts. If anyone has an idea, please do help me know it.

I am building a custom component where I am using the table component provided by Ant Design. For most of the parts, everything works as expected, however, there is a "tiny" issue.
I am using the "tree-data" (i.e. nested JSON) data to populate the Table component. Due to the fixed column size (which is a requirement) it has been noted during QA that the row`s label is not properly indented if it overflows (i.e. starts on a new row).
So my question is, how can indent the label such that when the label starts on a new line it starts from the initial indentation like this:
The GOAL would be to have the label "squeezed" within the green-dashed container.
On THIS LINK you can find a demo (the same as the one in ant design documentation with minor changes) which replicates the issue I am working on.
open the link
expand the first row (i.e. John Brown sr.) as it is expanded in the picture above.
You can apply display 'flex' to the column
// index.css
.name-column {
display: flex;
}
// demo.js
// column
...
...
...
{
title: "Name",
dataIndex: "name",
key: "name",
className: 'name-column'
},
...

I want to style a grid row after clicking on it. I get the grid row / item in the itemClickListener, but I need to avoid using grid.select(item). I have achieved the desired output which would highlight the row I clicked on with the grid select method, but this causes problems for my app since I do not want that row to be selected, but I want it to be just highlighted, e.g. apply a CSS style to said row. This is my code so far:
grid.addItemClickListener(e -> {
grid.deselectAll();
grid.select(e.getItem());
});
as well as:
grid.setStyleGenerator(row -> grid.getSelectedItems().contains(row)
? getRowSelectedStyle(row)
: null);
I cannot seem to find anything on the forums which could apply a style name for the clicked row.
You probably need to add a property to your item Bean, se "clicked".
Then you could do
grid.addItemClickListener(e -> {
e.getItem().setClicked(true);
grid.getDataProvider().refreshItem(e.getItem());
});
And
grid.setStyleGenerator(row -> row.isClicked()
? getRowSelectedStyle(row)
: null);
I have a table rendered using rhandsontable in R. I want to change the font color to red of a specific column. How can I do it ? I tried the following code, but it does not work
output$hot=renderRHandsontable({
rhandontable (table)%>%
hot_col("colum1", color = "red")
})
If you want to change the style of elements inside of your table (in your case it is the font color of each cell of a given column), you will need to use a bit of Javascript and write a renderer function that will do the job, like so:
# Toy data frame
table <- data.frame(a = 1:10, b = letters[1:10])
# Custom renderer function
color_renderer <- "
function(instance, td) {
Handsontable.renderers.TextRenderer.apply(this, arguments);
td.style.color = 'red';
}
"
rhandsontable(table) %>%
hot_col("b", renderer = color_renderer)
The function color_renderer() is saved as a string and will be used as the renderer argument of the hot_col()-function. Note the argument td I am using refers to the cell object of your table. td has several attributes, one is the style, which in turn has the attribute color.
Also make certain that you are using the correct Handsontable renderer. In my case, it is a TextRenderer but you may use different renderers based on the data type your column has.
For more information, refer to the Handsontable documentation.
I hope this helps.

i would like to have one list select that will have more than one style, i put two kinds of object's one is a group of users (bold), rest are users (italic or regular) is it possible to add style that will be added to part of added obj?
My code looks like this:
for(Usr usr: userSearchResult){
listSelect.addItem(usr);
}
listSelect.addStyleName("bold");
for (Gr gr : groupSearchResult) {
searchList.addItem(gr);
}
and also have style set in css correct similar to this
.v-select-bold .v-select-select {
font-weight:bold;}
i would be glad to solve this by myself but that was two days ago now i'm in a dot ;)
Thanks in advance for help!
You can store your row as a label with style. In the container there will be a label instance. There you can simply add the style.
Container container = new IndexedContainer();
container.addContainerProperty(NAME_PROPERTY, Label.class , "");
for (int i = 0; i <= 50 ; i++) {
Item item = container.addItem(i);
Label label = new Label(HashUtils.getRandomSalt());
label.addStyleName(style)
item.getItemProperty(NAME_PROPERTY).setValue();
}
return container;
You can't style rows of a ListSelect. You can use a Table component with one column to achieve a similar result. Table.setCellStyleGenerator method is used for differentiating styles for each cell (each row in your case).
I am new to DoJo development so this could be basic.
I have created an EnhancedDatagrid and it shows the data fine.
The data comes from an JSON store in a different page.
I have a button which causes that one new entry is created in the datastore and then my datagrid is 'refreshed'. This works fine.
But now i want only as the last step to change the style of the first row in my datagrid.
(I need to make the newly added row more visible.)
But i simply can't figure out how to get a handle on the first row in a datagrid.
...
grid = new dojox.grid.EnhancedGrid({
id: strId,
store: store,
structure: layout,
}, document.createElement('div'));
dojo.byId(placeHolder).appendChild(grid.domNode);
grid.startup();
var row = grid.getItem(0); // ---get the first row. How ? And how to apply new style ?
...
Thank you in advance.
Solved the problem like this:
dojo.connect(grid, 'onStyleRow', this, function (row) {
var item = grid.getItem(row.index);
if (row.index == 0) {
row.customClasses = "highlightRow";
row.customStyles += 'background-color:#FFB93F;';
}
});
I use the 'Claro' theme and it prevented me to set the background color of the row-cells.
The solution was to set the customClasses to a style like this:
.highlightRow tr
{
background-color: #FF6A00 !important;
}
Found part of the solution here: http://dojo-toolkit.33424.n3.nabble.com/row-customStyles-was-overwrite-by-claro-theme-td3763079.html
