Hi All
Using this link below I have been able to set the color of individual rows in a Perspective table based on the value of a cell. I would like to set the colors of individual cells. I can see that the script below is setting a style for the whole row. I have tried to loop through my dataset and assign a style to each cell without any luck. Please can someone point me in the right direction? Thanks!

output_json = []
style_orange = {"backgroundColor": "#F7901D"}
style_green = {"backgroundColor": "#00AA00"}
for row in range(value.getRowCount()):
row_object = {}
row_value = {}
row_style = {}
for col in range(value.getColumnCount()):
row_value[value.getColumnName(col)] = value.getValueAt(row, col)
row_object['value'] = row_value
if value.getColumnName(col) == 'container_type':
if value.getValueAt(row, col) == 'can':
row_style = style_orange
elif value.getValueAt(row, col) == 'bottle':
row_style = style_green
row_object['style'] = row_style
output_json.append(row_object)
return output_json
you have to set the style/value a “level” deeper, like so:
the row here is helsinki, the column is jakarta
for the example code it would be something like: it can be a bit cleaner but this should get you started xd
if value.getColumnName(col) == 'container_type':
if value.getValueAt(row, col) == 'can':
#style row to orange
row_style = style_orange
elif value.getValueAt(row, col) == 'bottle':
#style cel to green
row_object['value']['container_type'] ={'value':row_value['container_type'],'style':style_green}

Thanks! The following seems to work but I now need to sort the keys so that they are in the correct order.
output_json = []
style_red = {"backgroundColor": "red"}
style_green = {"backgroundColor": "green"}
style_gray = {"backgroundColor": "gray"}
for row in range(value.getRowCount()):
#Clear the row object
row_object = {}
for col in range(value.getColumnCount()):
cell_object = {}
cell_style = {}
# Add a key/value pair for the cell
cell_object['value']=value.getValueAt(row, col)
# Select the style
if value.getColumnName(col) == 'LED':
if value.getValueAt(row, col) == 'red':
cell_style = style_red
elif value.getValueAt(row, col) == 'green':
cell_style = style_green
elif value.getValueAt(row, col) == 'gray':
cell_style = style_gray
cell_object['style']=cell_style
#Add the cell object to the row object
row_object[value.getColumnName(col)]=cell_object
#Add the row_object to the output
output_json.append(row_object)
return output_json

it might be easier to use “getColumnNames()” instead of “getColumnCount()”, so you dont have to worry about sorting indexes
this:
for col in value.getColumnNames():
....
if col == 'LED':
...
row_object[col]=cell_object
instead of:
for col in range(value.getColumnCount()):
...
value.getColumnName(col) == 'LED'
...
row_object[value.getColumnName(col)]=cell_object

Thanks for your help. That has cleaned up the code a little. I’ll work on sorting the key order in the json string later.
output_json = []
style_red = {"backgroundColor": "red"}
style_green = {"backgroundColor": "green"}
style_gray = {"backgroundColor": "gray"}
for row in range(value.getRowCount()):
row_object = {}
for col in value.getColumnNames():
cell_object = {}
cell_style = {}
# Add a key/value pair for the cell
cell_object['value']=value.getValueAt(row, col)
# Select the style
if col == 'LED':
color = value.getValueAt(row, col)
if color == 'red':
cell_style = style_red
elif color == 'green':
cell_style = style_green
elif color == 'gray':
cell_style = style_gray
cell_object['style']=cell_style
#Add the cell object to the row object
row_object[col]=cell_object
#Add the row_object to the output
output_json.append(row_object)
return output_json
Golfed a bit:
def getStyle(row, col):
if col == 'LED':
color = value.getValueAt(row, col)
if color == 'red':
return {"backgroundColor": "red"}
elif color == 'green':
return {"backgroundColor": "green"}
elif color == 'gray':
return {"backgroundColor": "gray"}
return [
{
"value": value.getValueAt(row, col)
"style": getStyle(row, col)
for col in value.columnNames.sort()
}
for row in range(value.rowCount)
]

Hi. I tried to use your code in the tag binding transform for my table. I get “Error_Configuration”. The issue seems to be related to the for loops. Please can you explain how this is supposed to work? Thanks for the reply.
My (admittedly untested) code is using a Python feature called ‘comprehensions’ - specifically, a dictionary comprehension nested inside a list comprehension. It’s a sometimes-nicer way to construct repetitive objects like this - there’s no significant advantage over your already working solution.
I probably have a syntax error in there somewhere, the Error_Configuration may tell you more if you hover over it in the designer.
Thanks for the quick reply. I will read up on comprehensions.
Do you know how I can arrange the “columns” of my json into a specified order? I am not using any properties in the table, everything comes from the json. I have read a few posts but nothing seems to apply to my use case.

Your columns will be displayed in whatever order you have the objects in the top-level columns property:
You must match the field in each object to a column name in your actual data.

Got it - simple fix. Thanks again.
Hi,
I want to change only font color of only one column based on condition.
I tried table-data-query- named query- Add transform . but I am not getting.
I want the table like this with font color change on condition.(Target<Actual) change font color of Actual.
I am very sorry since it is urgent requirement for me I am posting the issue again here.
sorry for the inconvenience.
Please help and guide the steps
