spire | Powerful new number types and numeric abstractions | Functional Programming library

I'm working with Spire.XLS and I have to populate an excel file with different sheets, then the problem begins, I need to take out values from different sheets and export those together in the same dataGridView, to take the values I use the method sheet.Range[], it seems like spire.XLS as the command exportDataTable(), but in this case it shows something like this

And the problem with this one is that this doesn't maintain the cell background color nor the actual value of the formula in the last col, I'm open to other libraries as well if needed, but I need to figure this problem out

I'm working with Spire.XLS licenced pack and I need to find a way to set the values for a chart manually from a c# win form application, speaking about category labels to actual values to display inside, instead of being forced to use sheet.Range[], or at least be able to use single cell values separated one from another from a sheet and use those like an "extended range" for the values any idea if this is possible?

The development team is using Tomcat 7 on Ubuntu server. I downloaded that Tomcat from the server and deployed locally and it works okay.

Now, I developed a spring-boot module, wrapped it into WAR file and wanted to deploy it in the same Tomcat. However, catalina.bat run fails to start my spring-boot application. The original application (called ROOT) is working fine.

My pom.xml:

I have a project to combine multiple docx documents into 1 docx file using spring boot. I'm confused about using the poi library or E-iceblue's free Spire.Doc. I've managed to use those two libraries. And I'm more comfortable using the spire library because its use is simpler. What I want to ask is is it safe to use E-iceblue's free Spire.Doc library in a large project? Does it have a license?

Here are the dependencies and repositories in pom.xml file :

I'm trying to generate a Word document using Spire.Doc and download it. I can download the document, but it is empty. Does anyone have any idea why that is and can help me? This is my code:

I'm following the Default Mod Base tutorial and I stumbled on a problem. The game crashed when I try to start a new run as the Default:

I have this code:

I'm in the process of vetting a move to service mesh. While Istio and Consul Connect are certainly still in the cards, I'm leaning towards building up from a bit lower level with Linkerd and SPIFFE/SPIRE.

I want to build a 'hello world' mesh to test this architecture out. In this hello world mesh, I'd like to be able to issue certificates from SPIFFE/SPIRE that encode some kind of role. As you can probably tell, I'm new to service meshes. How would I implement roles? Are there any guides out there to help get me started?
